Abstract

It is very important to maintain the balanced output voltage waveforms under the unbalanced DC-link voltages in the four-switch three-phase inverter(FSTPI). In this paper, the improvement of output voltage waveforms is proposed with the aid of DC-link voltage ripple estimation. The proposed method can be implemented without the additional voltage sensor. The proposed method applied to the permanent magnet synchronous motor (PMSM) is simulated and experimented in order to verify its feasibility.
