A kind of motor driven systems based on driver module IPM
Technical field
The present invention relates to a kind of motor driven systems based on driver module IPM.
Background technology
Intelligent Power Module IPM (Intelligent Power Module) has many advantages with respect to IGBT (Insulated Gate Bipolar Transistor).It the is built-in gate driver circuit of IGBT; and the control power supply only needs the forward bias power supply and does not need the reverse bias power supply; simplified the design of peripheral circuit; realized control circuit CMOSization; reduced the power consumption of control circuit; and built-in fault detection and protective circuit; as: short circuit excess current, excess temperature, control line under-voltage etc.; so just reduced original design, trial-production, evaluation, design-calculated periodical duty repeatedly again, reduced because overload and misoperation bring the possibility of damage.
Summary of the invention
Goal of the invention of the present invention is to provide a kind of motor driven systems based on driver module IPM, effectively improves the integrated level and the reliability of motor driven systems.
Realize the object of the invention technical scheme:
A kind of motor driven systems based on driver module IPM, it is characterized in that: have the electric machine control master chip, the electric machine control master chip is connected with the entire car controller communication through communication module, electric machine control master chip signal output part connection interface module, driver module IPM, the signal input part of electric machine control master chip connects the signal output part of analog signal load module and digital signal load module respectively.
The beneficial effect that the present invention has:
The present invention has effectively improved the integrated level and the reliability of motor driven systems, has optimized system design.The present invention can be independent of other controllers of vehicle body, also can integrate with other controllers of vehicle body, in the time of as individual components, communicate, can communicate connection by the internal interface plug-in unit in the time of as integrated component by communication module and other car body controllers of car load.
The present invention has optimized system design; compare with conventional I GBT drive system; power unit only needs the output of 15V forward; reduced the design of two-way out-put supply; simultaneously; the respective drive circuit part can be reduced to circuit shown in Figure 2; reduced tradition and amplified output based on integrated chip design, driving; improved the integrated level of system, strengthened the stability of system design, certainly; because the inner integrated protective circuit of IPM; thereby simplified the processing of logic error circuit, and reduced cost simultaneously, saved time-to-market.
