Abstract

Further driving distance has been required in electric vehicles under the limited battery energy. Therefore, inverter which is one of the EV core technologies should secure a higher efficiency. Inverter efficiency is largely dependent on switching commutation. In this paper, inverter SVPWM control scheme with switching loss reduction is proposed by introduction of simplified switching sequence strategy. It is confirmed by simulation and experimental analyses that the proposed modulation scheme has a lower switching loss compared to the conventional 5-step switching sequence based modulations scheme.
