摘要
在全桥DC DC变换器PWM控制技术系统分类的基础上 ,对比分析了四种PWM控制技术的基本原理和特点。分析和实验结果表明 ,针对大功率逆变电源对控制电路的具体要求 ,电流型相移式PWM控制技术尤其适用于大功率全桥DC
On basis of classifying PWM control techniques in full-bridge DC/DC converter,the paper,compares the operating principle and features of the four kinds of PWM control techniques.According to the special considerations of control circuit in nigh-power switching power supply,the current-mode phase-shift control technique is more optimum for the high-power full-bridge DC/DC converter.
