Electric vehicles and hybrid electric vehicles are powered by an electric motor supplied by a rechargeable energy storage system. Several schemes to implement the propulsion system are already available, as well as several solutions to recharge the power accumulators. The standard solutions consist of a DC-AC converter that operates in bidirectional mode for both the propulsion and the regeneration phases. A bidirectional DC-DC converter is implemented when very high power rating is requested. This converter is inserted between the high-voltage battery pack and the main inverter, in order to step up the DC bus voltage coming from the battery pack.
The embedded electronics must have high reliability standards to ensure the best power usage under all conditions. With its broad portfolio of power switches (IGBTs, MOSFETs), coupled with its ICs and microcontrollers, ST ensures the best solutions for your electric traction application.
