Abstract

Inverter with sinusoidal pulse width modulation in the operation of certain moments of the inductor current ripple is smaller, still maintain a switch with higher frequency, which will undoubtedly increase the loss of inverter unnecessarily. In this paper, a new control method of the inverter switching frequency is proposed. In this method, , inverter switching frequency is modified, while inductor current ripple peak to peak value is kept constant, in order to reduce the switching loss of the inverter power devices. Small signal modeling and analysis show that the introduction of inverter switching frequency control will not affect the steady-state and dynamic performance of the loop control system. The effectiveness of the proposed control method is verified by both simulation and experiment.
