Research on VSCF Power Generation System Based on Incorporation Design of HESM and TSMC

This paper introduces the application of hybrid excitation synchronous machine (HESM) and two-stage matrix converter (TSMC) in variable-speed constant-frequency (VSCF) power system. A H-bridge is employed for excitation power circuit, which is combined with two-stage matrix converter (TSMC) as a module by sharing the dc-link of TSMC. This paper analyzed the modulation strategy of the system in two cases; the modulation strategy is simulated by MATLAB software. The simulation results demonstrated that the system has the excellent generation performance with wide range of the speed of HESM.
