Starter-Generator Design and Dynamic Processes Simulation for HEVs

Hybrid vehicle is characterized by the unification of the two functional systems, namely, the generating electricity system in the vehicle's electrical system and the starter system of the internal combustion engine (ICE). The development of power electronics, as well as the growth of power consumed by vehicles, allow us to combine a starter system and power supply in one power unit - the starter-generator. It is the combination of the AC machine (ACM) and the power electronic converter. AC outs of the electronic power converter connected to the ACM stator. DC outs of this converter connected to the battery and (or) capacitive energy storage (CES). The ACM starts the ICE in the motor mode. In electric vehicles, the starter-generator allows recuperating electric energy and acts as a part of braking system. The article is devoted to the design of the induction starter-generator for the Russian automobile “LADA”. The result of dynamic processes simulation is given.
