Description
Technical field
The utility model relates to the power model in high-power converter main circuit, is specially a kind of novel high-power rectification, inverted power module.
Background technology
Along with the fast development of national economy, power electronic technology is more and more extensive in the application of alternating current drive technology, and the development trend of power electronic technology is high frequency, modularization, digitlization and environmental protection.The development of power electronic technology has greatly promoted the development of ac speed control technology, the high power contravariant that can be competent at ac speed control technology mainly contains turn-off thyristor (GTO), insulated gate bipolar transistor (IGBT), power transistor (GTR) etc. with device, wherein IGBT is widely used, obtained development rapidly, its performance is also improved reliable more.Take IGBT as rectification, the power model of inversion device has obtained increasing application in high-power converter, make the AC speed regulating main circuit hardware configuration of high-power converter realize modularization, rectification in the main circuit of high-power converter, inversion and chopper circuit all can be realized by corresponding power model, in high-power converter, input, output is large voltage and large electric current, in power model, rectification and inverter bridge leg all need the IGBT of two-tube parallel connection, therefore in rectification, on the two sides of the water-cooling base plate of inverted power module, all can only fix respectively a rectifying bridge arm and an inverter bridge leg, single rectification, the structure of inverted power module as shown in Figure 1, in the main circuit of high-power converter, just need three such rectifications, inverted power module, and three rectifications in main circuit, the selection of the model of the IGBT in the rectification unit of inverted power module is different, three rectifications, cannot phase trans-substitution between inverted power module, high-power converter has just increased spare unit kind, when high-power converter is worked, rectification, rectification unit in inverted power module and the operating voltage of inversion unit, operating current and switching frequency are all not identical, rectification, the both sides caloric value of the water-cooling base plate of inverted power module is just different, on water-cooling base plate, must consider that the unit of caloric value maximum determines discharge and flow velocity during the design of cooling circuit, the water-cooling system of designing like this has very large surplus to the less unit of caloric value, caused the cooling power of cooling system to be greater than the cooling power of actual demand, make the type selecting of the design of cooling circuit and power device be difficult to balance.
Summary of the invention
The utility model, in order to solve existing rectification, inverted power module interchangeability based on IGBT poor and cooling power and the unmatched problem of actual demand power, provides a kind of novel high-power rectification, inverted power module.
The utility model is to adopt following technical scheme to realize: a kind of novel high-power rectification, inverted power module, comprise water-cooling base plate, one side of water-cooling base plate is fixed with an inverter bridge leg, and the another side of water-cooling base plate is fixed with two rectifying bridge arms that are comprised of four diodes.
In the main circuit of high-power converter, adopt three these power models, can realize 12 pulsating wave rectification, the alternating current of the inversion unit output three-phase variable voltage variable frequency in main circuit is to load; In main circuit, in three power models, rectification unit device is all diode, therefore between three power models, can exchange use, has improved installation serious forgiveness, has reduced the spare unit kind of high-power converter; On a power model, be fixed with two rectifying bridge arms, rectification unit on three power models forms 12 pulsating wave rectification, make on power model rectification unit and inversion unit power division even, on power model, the caloric value of rectification unit and inversion unit is basic identical, make the design of cooling system of water-cooling base plate more efficient, the cooling power of water-cooling base plate and actual demand power mate mutually.
The utlity model has following beneficial effect:
1. strengthen the interchangeability of power model, reduced spare unit kind; Avoid difference in functionality module that dislocation is installed, improved serious forgiveness; Identical power model is more conducive to arranging of locus, and cabinet body structure design difficulty is reduced, and it is reasonable that space availability ratio is more tending towards;
2, identical power model heat radiation requires basic identical, make the design of cooling circuit more efficient, cooling circuit is with regard to do not need must be for there being the module of the highest heat radiation requirement to design, reduced the requirement to coolant rate flow velocity, reduced cooling circuit circulation power bearing power, made cooling circuit simpler efficient;
3, power division is even, makes the selection of power component performance parameter more be tending towards reasonable.While selecting power component, just avoided in order to meet the waste of the power device performance that maximum power requires and cause while selecting equal-wattage device.
