摘要
电源控制器(PCU)在电解加工系统控制精度及其保护中越来越重要,已从模拟IC走向数字控制。以TMS320F28027为核心设计出一种高频高能脉冲电源,采用新颖简单的电流和脉冲电压检测方法,实现了电压、电流模式切换控制和频率、占空比的可调,在高频大电流脉冲电源中具有较好的精度和稳定度。
The power controller is more and more important in electrochemical machining system＇s for control of precision＂ and its protection. Its way of control turn analog IC into digital control. In this paper, TMS320F28027, as the core, a kind of high frequency, high energy pulse power supply is designed. Adopting simple current and pulse voltage detection methods, voltage, current mode switch control, frequency and duty ratio adjusting are realized in pulse power, and it have high frequency, high current pulse. The generator has good accuracy and stability.
