Replace the good choice of detached power parts of an apparatus

Domain of automation of electric power drive is taller and taller to the performance demand of power parts of an apparatus nowadays. Compositive degree of tall, dependability is good and low-cost electric power parts of an apparatus more and more get the favour of people. Drive of the UPS that surpasses meter of small-power in accusing a company to be aimed at, electric machinery, electric welder and inductive heater rolled out SEMITOP series module, it is OK many chip, wait like IGBT, diode and input commutate bridge compositive in the module that becomes independent in. Surpass meter of SEMITOP series module that accuses a company to roll out many chip compositive in the module that becomes independent in. Current, SEMITOP series already had SEMITOP1, SEMITOP2, SEMITOP3 and newest SEMITOP4 kind product. Every kinds of product all has 2 compression order and degree: 600V and 1200V, chip of IGBT of type of use dispute break-through groove. New the power when the SEMITOP4 drive electric machinery that roll out can amount to 22kW, it encloses newest IGBT chip in to be packed compactly in, also be current SEMITOP1, 2, the continuance product of 3 module. Product characteristic 1.

Of sex of low thermal resistance medicinal powder hot structure SEMITOP is used come loose distinctly hot structure technology, did not have the cupreous substrate of traditional power module, use radical of pottery and porcelain at the same time piece make insulating material, the result that brings from this is lower thermal resistance and higher reliability. Medicinal powder if hot structure pursues 1 with the graph 2 are shown. Graph 1 common semiconductor product comes loose of product of series of 2SEMITOP of hot knot composition of a picture medicinal powder hot structure 2.

Height is compositive the product of structural SEMITOP series that turn always shares 4 to enclose dimension, include SEMITOP1, SEMITOP2, SEMITOP3 and SEMITOP4, and unite height be 12mm, OK and most compositive the circuit structure that is equivalent to 21 detached parts of an apparatus, include rectification, apply the brake, inversion and heat to conduct the circuit function such as feeling among them (see a picture 3) . Graph 3 SEMITOP is compositive the circuit structure Nextpage3 of 21 detached parts of an apparatus.

The installation that installs product of handy SEMITOP series is very convenient, need an intermediate screw to be able to install radiator to go up only (see a picture 4) . Graph the comparison of the installation of 4SEMITOP and detached power parts of an apparatus what SEMITOP uses is the patent SKiiP technology that contest rice accuses (technology of crimp of SKiiP technology = + do not take substrate + optimized chip distributings) . This product is first the purpose of research and development is to be in all sorts of need are tall compositive degree, the applied circumstance of insulation and high reliability can replace detached power parts of an apparatus for the choice. 1.

SEMITOP score is had from power parts of an apparatus taller compositive spend SEMITOP to have the develop that can ask according to the client and designs neatly to attack structure and it is tall compositive spent module. A typical case is it can rectification, apply the brake and inversion all and compositive in a module (referenced graph 1 with the graph 2) . Have CIB (CIB= commutate is unit + inversion is unit + apply the brake is unit) , develop attacks the individual SEMITOP module that the structure carries temperature sensor is equal to parts of an apparatus of 21 detached power (see a picture 5) . Will look from this bit, SEMITOP far score is compact from power parts of an apparatus, economic space, and facilitate install. Module of graph 5SEMITOP CIB is equal to parts of an apparatus of 21 schism power 2.

Because SEMITOP does not take substrate,SEMITOP score has lower thermal resistance and high reliability from power parts of an apparatus, because this is on thermal conductivity and dependability greatly excel depart parts of an apparatus. As a result of,NextpageSEMITOP has lower than detached power parts of an apparatus much thermal resistance is: (1) the structure that does not have substrate reduced the number of plies between chip and carbon fin. (2) the insulating material that score of underlay of pottery and porcelain uses from place of power parts of an apparatus (if be isolated from piece) have better hot conductibility, because this makes,the knot of SEMITOP wants to the thermal resistance of radiator under detached power parts of an apparatus. As a result of,SEMITOP has better than detached power parts of an apparatus reliability is: (1) radical of pottery and porcelain piece have and the hot coefficient of expansion of likeness of silicon of IGBT chip data (CTE) . (2) used crimp technology. Because solder,be done not have and make the large area of material of different hot coefficient of expansion rigid join. Oneself structure is OK amortize all sorts of mechanical stress. Because the silicon chip of pottery and porcelain and IGBT is hot coefficient of expansion is very similar, unapt difference is too big and it is easy that the heat of the semiconductor in making sure long heat circulates expands exhaustion and rupture. This also are SEMITOP the advantage to detached power parts of an apparatus, it is higher reliability. 3.

SEMITOP is insulation system and detached power parts of an apparatus does not have the underlay of pottery and porcelain in insulation SEMITOP module to have very admirable insulation property and hot property. photograph comparing, detached power parts of an apparatus was not isolated from. The user when will different detached power parts of an apparatus assembles a radiator to go up needs to assure to maintain insulating properties in part of different parts of an apparatus. And this is a very big drawback. Because of high-pressured insulating material, if be isolated from piece wait to have taller thermal resistance, such bringing about medicinal powder heat energy force is poorer. The isolation voltage of SEMITOP standard can achieve 3000V. Go up at this o'clock in insulation, SEMITOP also has an advantage than detached power parts of an apparatus. 4.

SEMITOP photograph bisect is very competitive from price of power parts of an apparatus and installation cost is lower above all, when the cost of the power parts of an apparatus that compares two kinds of different structures, need with same applied circumstance is premise, the selection goes applicable parts of an apparatus, compare the price next. Because SEMITOP is a module that already was isolated from, and according to having very low thermal resistance, so we should not compare the detached parts of an apparatus of grade of same electric current and SEMITOP. For instance the applied circumstance of the detached parts of an apparatus of 15A, be like those who use SEMITOP simply 10A or social estate of smaller electric current can. Next, to analyse the value better, we will discuss next detail that cost in assemble deep. Realize inversion of a three-phase, if use detached power parts of an apparatus, even if is in best IGBT is compositive below the circumstance of diode of follow on current, also need 6 6 6 parts of an apparatus, screw, gasket and 6 insulating material. But if we use SEMITOP, need only mere one pace is OK very relaxed install whole inverter on radiator, reduced installation time greatly so, also lowered constructional failure rate at the same time. SEMITOP can offer following advantage for the user: Save installation time, need a screw to be able to install module radiator to go up only; Installation material decreases, assemble cost to reduce; Do not want additional insulating material, saved expenditure; Reduced size (smaller PCB, smaller radiator) with the processing to radiator; Component decreases, much better hot coefficient of expansion brings high reliability. the indispensable expenditure when detached power parts of an apparatus is assembled the consideration goes in, SEMITOP is a kind of special economy and the solution that returns a client to bring more to go to the lavatory. The simple application SEMITOP of SEMITOP tastes function, height in view of its reliable yield compositive with simple and easy installation, and the circuit structure of agile diversity, apply to a variety of application circumstances, include electric welder, medium induction of drive of small-power electric machinery heats control of UPS, process, automation application and electric car. The SEMITOP module that uses contest rice to accuse in the design application of electric welder inverter will design welder inverter, welder unit volume can be reduced, your totle drilling cost also can reduce 20% ～ greatly 30% . Parts of an apparatus of schism of SEMITOP photograph comparing and the module of the substrate that carry copper (be isolated from) thermal resistance is a lot of lower. It has first-rate to come loose hot property, and can use the IGBT with a bit lower rank of an electric current, your cost is reduced. In addition, compare same chip electric current, SEMITOP can export bigger electricity, loss efficiency is low. SEMITOP module is compositive degree tall, it is OK many chip, for example IGBT, diode, input commutate bridge compositive in an individual module. SEMITOP has huge advantage to be able to replace detached power parts of an apparatus in each respect such as dependability, life and price. SEMITOP is a kind when contest rice accuses company numerous semiconductor to enclose a product, with its Gao Ke of low thermal resistance relies on gender, dimension small compositive degree of tall, installation extremely simple and easy and convenient wait for an advantage and get applied extensively. Epilogue SEMITOP score leaves power parts of an apparatus compositive to spend taller, dependability is stronger, lower cost and be isolated from. It is the admirable substitute of detached power parts of an apparatus, agile and changeful develop attacks the structure can come true in SEMITOP individual module. Accuse like contest rice " service ＋ innovates " concept, SEMITOP is to be being searched tall compositive degree, the optimal choice of the user of dependability and parts of an apparatus of low cost power.
