面向恒功率负载Boost变换器输出电压调节的PWM非线性控制与负载功率估计

This article presents a nonlinear control based on pulsewidth modulation (PWM) and an estimation mechanism of the output power to regulate the output voltage of a boost converter supplying a constant power load (CPL). The controller uses three parameters $K_{p}$, $K_{E}$, and $K_{A}$ lending the regulator an adaptive nature. The behavior of the latter can be expressed in terms of the dynamic descr...
