图腾柱PFC中零电流检测的无硬件多变量协同功率定位方法

This letter proposes a multivariable coordinated power positioning method (MVCPPM) to mitigate zero-current detection failure and system instability caused by multicycle current errors accumulation at quasi-MHz switching frequencies. Unlike conventional single-variable positioning or hardware-assisted approaches, MVCPPM constructs a dynamic power positioning model by real-time identification of th...
