Abstract

A switch less power converter topology for SRG is proposed in this paper. Under high-speed operation and continuous conduction mode （CCM）, the working process of excitation stage and generation stage of the new power converter is analyzed. At the same time, compared with the traditional asymmetrical half-bridge power converter based on the switching angle control, the same results of excitation and power generation processes are obtained. According to the simulation and experimental results, the phase voltage and phase current of the new power converter at high speed CCM are consistent with the theoretical analysis. The constraints of speed, excitation voltage, generation voltage and power are obtained, and then the output power can be optimized by adjusting the excitation voltage and generation voltage. Compared with the asymmetric half-bridge power converter controlled by switching angle, the new power converter has the same generation capacity. Finally, taking the application of variable speed wind power as an example, the control strategy is given, without rotor position detection and wind speed detection, and without pitch angle adjustment above the base speed. The simulation results show the effectiveness of the proposed power converter and its control strategy in high-speed CCM operation.
