Abstract

The paper deals with a simplified configuration of series HEV hybrid vehicles. Simplification consists of the downsizing of auxiliary 4QC converter needed for hybrid operational modes. Besides, operation in autonomous traction accu-battery modes uses direct 0x5 configuration of traction 3x5 McX matrix converter. Such a configuration can be derived from that main traction converter. Major advantages of simplified connection are beside smaller 4QC converter size – possible little bit better efficiency of the HEV powertrain. Chosen operational modes of modelling and simulation of traction powertrain configuration are focused on start-up and traction drive of HEV powered by ICE, start-up of ICE powered by AB accu-battery using SG as a starter, and traction drive powered by AB accu-battery and braking of traction motor moving energy into accu- battery AB. The results of all simulation experiments are given in the paper.
