Dynamic Overmodulation Strategies of Two Phase Full Bridge Inverter

2상 풀브릿지 인버터의 동적 과변조 기법

In this paper, dynamic overmodulation strategies are proposed for two phase full bridge inverter. The four step operation to use maximum voltage in limited DC link is described and minimum distance, same angle and minimum switching state overmodulation techniques are presented. The simple scalar arithmetic based algorithms are proposed to implement the overmodulation techniques. Simulation results demonstrate the effectiveness of the proposed algorithms.
