The simulation results show: the excitation controlling system has the high stability and voltageregulation precision, fast dynamic process response and better adaptability to practical production.
The concerted control strategy of rectifier and inverter is analyzed to keep high modulation degree of SPWM, which achieves quick response and high resolution of excitation voltageregulation.
SVPWM technique have many good qualities, such as less pulsating torque, high usage of DC bus voltage, less switching loss, better high-speed regulation performance.
