摘　　要：研究提出了一种新型的低纹波高压直流电源电路结构,该电源采用电压互补的工作原理,将两路独立输出电压相同、相位相差90°的半桥逆变电路并联后输出,使其输出电压并联互补,以达到减小直流输出电压脉动的目的.在介绍该电源工作原理和控制方式基础上,并依据该方案研制了一台小功率样机,结合实验波形,证实了该方案的可行性.We design a new current power supply circuit with low ripple and high voltage.The power supply works under the principle of complementary voltage,which parallels two self-contained inverting circuits of half-bridge with the same output voltage and phase difference 90°.The paralleling connection of the output voltage reduces the ripple of output voltage.We introduce the principle and control mode of our power supply and manufacture a prototype low power machine.The results of the experiment of the prototype machine show that the design is feasible.
