High speed and efficient change soldering is contemporary soldering development direction, it is the only way that implementation modernization solders. Digitlizing welder is efficient solder and solder the foundation that automation solders. Digitlization handles technology and the product that arc solder craft combines as digital signal, caused the wide attention of the personage inside course of study. The implementation means that digitlizes welder of soldering concept and its characteristic, digitlization and digitlization welder receive manufacturing technology to rising to urge action certainly to whole solder. Also driving at the same time solder the mainest base of the industry---The development of power semiconductor technology, high quality, gao Ke relies on the delegate product of power electron of the gender----IGBT its technology, also be get rid of the stale and bring forth the fresh, change quickly. Regard power as the delegate of electronic super-heavyweight---German contest rice accuses to be solder of the industry 3 drive carriage: Below Tang Shansong, shandong abstruse too, beijing times---They are contemporary solder the technology presses the ala that went up to fly. Digitlization welder technology basically includes 3 fields: The digitlization of main circuit, solder from imitate type namely power source solders to switch type type of power source, inversion solders power source main circuit, developing what apply in great quantities now is IGBT, MOSFET or bipolar inverter of solder of transistor type arc. And involve solder method and material range are wider and wider, power is greater and greater, opposite volume is minorrer and minorrer. Control the digitlization of circuit, the technical application development of this respect is very fast. the construction that controls a system, digitlization solders the control part of power source by sheet piece machine and DSP (digital signal processor) form jointly, to giving signal shedding, parameter feedback shedding and net press signal to shed integrated processing and operation, control, achieve solder the digitlization of power source, informatization, flexible the control that turn. Drive circuit is the core part in solutions of any system of electric power electron. The SKYPER concept that surpasses rice to accuse a company to put forward is mixed for different IGBT module one is offerred between controller agile and the interface that can expand. Contest rice accused a company to define a kind new, the interface means between the drive circuit that faces future and controller, in order to satisfy all sorts of requirements. All signal have specific definition and very specific function. The most important is its are used simple. Of interface signal arrange means to be able to make its join the relation differentiates logically for different group. Insert what the arrangement of the signal on the needle reflected these sets to differentiate. Although this interface included all character that can expand drive circuit asks, but drive circuit itself also can use very little basic signal only (TOP, BOT, HALT) will realize control. The core of this drive circuit is the sheet that is based on contest rice to accuse a company to develop piece type drive is special integrated circuit. Graph 2 pictures gave corresponding block diagram. This IC is compositive short pulse is restrained, pulse plastics, owe pressure monitor, breakdown detects, the function such as circuit of drive of transformer of lock of memory and output, each other, DC/DC. Plan of drive of SEMiX power module includes a join spy to decide module transfer the current drive core of circuit board and standard version or advanced version. Drive core and transfer board use insert type join namely, get module of an intelligence power so. SKYPER has complete power terminal, can module of IGBT of drive SEMiX 　 . Differ according to the power semiconductor device of drive, switch frequency can amount to 20kHz, its occupy sky comparing to be able to adjust arbitrarily. The change transfers board the module that the grid resistance that go up can realize drive to differ. SEMiX and SKYPER - the IPM that the power limits of tradition of combined-type IPM plan is 2kW ～ 10kW (intelligent power module) plan is with module inside compositive drive circuit is a characteristic. The accurate potential that these drive circuit used such as n to change line keeps apart the electric segregation with true and rather than. And for the power limits to 10kW above, although also exist compositive the power module plan of drive circuit, but its insufficient place depends on them doing not have electric segregation at all, this means need to increase exterior and electric segregation, still must develop an interface board and power source board. In combined-type IPM drive circuit is not a fixed compositive component, contrary, drive component installation is on power module, formed system of so called intelligence. Differ with traditional IPM plan, the SKYPER that is based on SEMiX platform (the drive circuit that is used at combined-type IPM) compositive the part that can implement completely electric segregation (DC/DC transformer and pulse transformer) . An installation is in half bridge of SEMiX3 the SKYPER on module. When assembling, do not need to undertake any solder, cable bond or the join that insert a needle. Contrary, the bedspring contact of SEMiX and touch the electric connection that accepts a technology to be applied at SKYPER and SEMiX3 module acceptedly, transfer suitably plus board the IPM that formed a 6 canals to enclose. Because drive is simple, and the core of drive circuit applicably at any IGBT platform (for example SEMITRANS, SEMiX) , surpassing program of meter of this kind of drive that controls a company is a kind of when apply engineer group to offer a technology to support by the SEMIKRON that exceeds 50 branches in the whole world outstanding electric power electron solution.
