| 摘 要： | 阐述了一种非线性载波(Nonlinear-carrier)控制的PFC电路,该电路与传统单级功率因数校正电路相比不再需要输入电压、电流采样以及复杂的模拟乘法器和电流误差放大器电路。非线性载波(NLC)控制理论基于对变换器元件(开关管、二极管或电感)的电流检测,并与非线性载波比较获得开关管PWM波形来实施控制。

| Abstract: | This paper introduces a kind of nonlinear-carrier(NLC) controller for high power factor boost converters.Using the NLC controller,input line voltage and current sensing,error amplifier in the current shaping loop,and analog multiplier/divider are eliminated.In the NLC controller,the switch duty ratio is determined by comparing an integrated current waveform which based on the integration of a current signal(from switch,diode,or inductor current) with a periodic nonlinear-carrier waveform. |
