Based on them , in this thesis , the one cycle control theory was successfully applied to the detection and control of apf for the first time . an apf using a novel unified constant - frequency integration control method was presented . the method employs an integrator with reset as its core component to achieve the detection and control of distortion current for apf at the same time 文中导出apf功率开关占空比必须满足的控制目标方程、求出apf主电路的稳态模型、建立了通用常频积分复位控制apf的数学模型，用简单的模拟电路实现apf的通用常频积分复位控制电路和通用常频积分复位控制apf系统。
