摘　　要：提出了一种单周期控制的谐振开关电容变换器。对运用单周控制技术与PWM控制的谐振开关电容变换器进行了对比仿真分析。单周控制比较适合用于直接控制谐振开关网络的电荷量,而且计算、设计方法简便,具备良好的动态响应和抗电源干扰强等优点。对仿真分析结果进行了对比试验验证。A switched capacitor resonant converter based on one-cycle control was presented. Comparative simulation and analysis were made on switched capacitor resonant converters using one-cycle control and PWM control techniques. The one-cycle control technique is suitable for directly controlling charge conversion variables of the switched capacitor resonant converter, and it has excellent system transient response and anti-disturbance characteristics, The calculation method is simple and convenient. Both theoretical analysis and experiments indicated that the one cycle control technique is feasible.
