| 摘 要： | 详细分析了Buck型和Boost型AC/AC变换器的工作原理及其控制方法,在此基础上提出了一种新型级联式Buck-Boost AC/AC变换器及其三模式控制策略.三模式控制策略是比较输入电压与基准输出电压的大小,使得变换器只有3种工作模式:Buck模式、Boost模式和滤波模式.该电路虽然由Buck型和Boost型AC/AC变换器2级变换器级联而成,并采用2级占空比调制,但实际上最多只存在一级功率变换,具有控制简单、变换效率高、开关管电压应力低等优点.仿真结果证明了级联式Buck-Boost AC/AC变换器及其控制策略的可行性和理论分析的正确性.

| Abstract: | The operating principle and control method of Buck-type and Boost-type AC/AC converters are analyzed,and a cascaded Buck-Boost AC/AC converter and its three-mode control strategy are proposed.It compares the input voltage with reference output voltage,resulting in three operating modes:Buck,Boost and filter.Though the circuit comprises of the cascaded Buck-type and Boost-type AC/AC converters with two-stage duty cycle modulation,there is only one-stage power conversion.Its control is simple,efficiency is hi... |
