摘要
介绍了一种适用于电容器快速充电的高压变频恒流充电电源,它采用智能功率模块IPM和全桥串联谐振式变换电路,依靠电流反馈信号来控制开关频率的升高以保持充电电流的恒定。实际运行表明该电源恒流效果好,工作稳定可靠。
A constant current high voltage power supply for charging the capacitor with variable switch frequency is described. Full-bridge series resonant topology and intelligent power modules (IPM) are used, and the switch frequency is controlled by the feedback signal of the resonant current to keep the charging current constant. The experimental results and practical operation show that the power supply has accurate constant charging current and high reliability.
