| Abstract: | According to different needs of direct starting and fast variable-frequency soft starting for AC motor which used to drive AC electrical oil pump equipped in ship power generators, this paper presents a new design method based on DSP control for special inverter starting power supply. This power supply has two-lever power transform circuits: boost and inverter. Variable parameter PI control is used to improve dynamic response ability of the boost circuit. SVPWM is used to enhance the DC line voltage utiliza... |
