摘　　要：舰船电站配备有交流电动滑油泵用交流电动机,对交流电机有直接启动和快速变频软启动的不同要求,本文给出了一种基于DSP全数字化控制的交流电机专用逆变启动电源设计方法。该逆变启动电源具有升压和逆变两级功率变换,升压电路采用变参数PI控制以提高动态响应能力,逆变电路具有输出电压闭环控制环节,并采用SVPWM调制技术提高直流母线电压利用率和改善逆变输出电压波形。本文对电源的系统结构、工作原理及控制策略进行了介绍,目前该电源已交付使用。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 utilization and improve the output voltage waveform of the inverter circuit. The structure and principle of the power supply, control strategy are introduced. This power supply has been used in engineering.
