| Abstract: | This article applied dual pulse width modulation (PWM) with the excellent input and the output feature to control AC-DC-AC inverters as the excitation power supply for AC excited generator. Through the simulation experiment, it was proved that dual-channel excitation controlling strategy based on dynamic synchronous shaft decoupling could implement the independent regulation of the AC excited generator active power, reactive power and rotating speed. The dual PWM converter had many advantages such as bidire... |
