摘　　要：论述了一种应用于电镀的双峰脉冲电源。由于负载的不确定性和非线性,该电源采用模糊PID对电流幅值进行闭环控制,控制硬件以TMS320LF2407DSP为核心。为减少开关损耗,DC/DC变换电路采用软开关技术。实验结果表明,该电源能够输出幅值、频率、脉宽连续可调并且幅值稳定的双峰脉冲电流。Introduced a pulse power supply with two peaks for plating. Because the controlled model was nonlinear and uncertain, the pulse power supply adopted fuzzy-PID controller. TMS320LF2407 DSP chip was the core in the control circuit. It used soft switching technology in the DC/DC converter in order to decrease turn-off losses. The experiment results show that the pulse power supply can generate two peaks pulse current with continuously adjusted peak, pulse-width ,frequency.
