Description
Technical field
The utility model relates to IGBT application field more particularly to a kind of busbar power modules based on 62mmIGBT.
Background technique
It is especially past during doing power battery electric performance test since the IGBT of 62mm has splendid stability
Toward the application that will appear high voltage-small current and low-voltage, high-current, in order to guarantee that equipment performance often directly selects single current transformer function
Rate device completes power conversion.But the stray inductance of current transformer can make to generate higher voltage point between the collection of IGBT, emitter-base bandgap grading
Peak even results in insulated gate bipolar transistor IGBT damage to cause biggish electromagnetic interference.Therefore it uses in systems
Peak voltage Absorption Capacitance and the standard configuration that configuration high voltage direct current Support Capacitor works at (IGBT) nearby.However, using spike
The auxiliary capacitors such as voltage Absorption Capacitance and high voltage direct current Support Capacitor will increase the stray inductance between IGBT and auxiliary circuit, nothing
Method reduces electromagnetic interference, and it is even more impossible to guarantee the stability of current transformer core power transformation device.As can reducing to the maximum extent
Line connection between IGBT and auxiliary capacitor, then can reduce the stray inductance between IGBT and auxiliary circuit well.
Utility model content
Technical problem to be solved in the utility model is that overcome the deficiencies of the prior art and provide a kind of structure simple, anti-
Interference performance is strong and the stable busbar power modules based on 62mmIGBT of performance.
The technical scheme adopted by the utility model is the utility model includes 62mmIGBT module, high voltage direct current support
Capacitor and peak voltage Absorption Capacitance, it further includes DC master row, and one of the DC master row is arranged in the IGBT module
On side, the high voltage direct current Support Capacitor and the peak voltage Absorption Capacitance are arranged at another of the DC master row
On side, radiator is provided on the downside of the IGBT module.
Above scheme makes IGBT module, high voltage direct current Support Capacitor and peak voltage as it can be seen that by the setting of DC master row
Absorption Capacitance is directly connected by DC master row, and the line connection reduced between IGBT and auxiliary capacitor is considerably reduced, from
And the stray inductance between IGBT and auxiliary circuit and peak voltage are efficiently reduced, improve the anti-interference ability of mould group and steady
Determine reliability, while also avoiding due to multi-thread connection bring potential faults；In addition, being compared with common wiring, using straight
Stream this connection type of busbar reduces stray inductance, the response speed of the small electric current of stray electrical sensibility reciprocal faster, and DC master row
The common wiring of resistance ratio resistance it is much smaller, the corresponding speed of electric current is further improved, so current response rate
Fastly, and then the control precision of electric current is improved, promotes the Control platform of entire mould group；In addition, the introducing of DC master row can be big
The earth simplifies installation and debugging process, and is convenient for device maintenance, relatively low to reduce costs.
Further, the DC master row is formed by stacking by independent two laminations, is provided on two laminations
IGBT connecting hole, several mounting holes and row wire terminal, after being stacked in overlapping described in two, the row wire terminal is arranged in a staggered manner, and two
Insulating layer is provided between a lamination.
Above scheme, so that structure is more compact, also saves the interior of module as it can be seen that by the overlapping settings of two laminations
Portion space provides guarantee to increase auxiliary capacitor.
Still further, being fixedly connected between the DC master row and the radiator by the way that epoxy plate is arranged.Thus may be used
See, by the setting of epoxy plate, both ensure that insulation performance, also enhance the stability of mould group, while guaranteeing the use of mould group
Service life.
Again further, the end of the radiator is provided with radiator fan.It can be seen that setting by radiator fan
It sets and enhances heat dissipation effect.
In addition, the quantity of the high voltage direct current Support Capacitor is set as four.It can be seen that the high voltage direct current branch of multi-quantity
Support capacitor improves proof voltage, resistance to galvanic, temperature performance, charge/discharge speed and the service life of mould group, also improves
The safety anti-explosive stability of entire mould group.
