摘　　要：提出了一种采用新型DSP控制的相移式的高压开关电源方案,其特点是采用了新型的DSP取代了传统的模拟移相控制电路。文中讨论了这种DSP控制芯片的特点,设计方法,给出了控制的算法的数学模型,介绍了采用这种DSP控制的20 kV/30 kW的电流耦合型高压开关电源。A new phase-shifting high voltage switching power supply based on DSP was presented in this paper. DSP circuit is used in this concept to replace the traditional analog phase-shift control circuit. The character istics of the DSP and the design of control circuit are introduced, and the mathematical model of the control arithmetic is provided. Finally, an example of a 20 kV/30 kW current-coupling high voltage switching power supply using this DSP control is given.
