In August Continental AG expects to introduce a smaller and more powerful version of its electronic power controller for hybrid and all-electric vehicles.
Conti already supplies second-generation power electronics to five European carmakers. The company says its next-generation system is six times as powerful, one-third lighter and "considerably" cheaper in terms of price per kilowatt.
The function of a power electronics device is to convert direct current from the battery into three-phase alternating current for the traction motor. The unit also controls the motor by regulating amperage and frequency. It can reverse polarity, thereby enabling an EV to back up. During regenerative braking, the system converts alternating current from the motor into direct current used to charge the vehicle's battery. Power electronics also provide a 12-volt feed to such vehicle systems as air conditioning, lighting and infotainment.
Conti's modular and scalable system combines an inverter and DC/DC converter within the same housing. The company says its design can be used across the entire passenger vehicle spectrum and with both hybrid and all-electric powertrains.
