为改善实际Boost变换器在大信号扰动下的控制性能,以CCM非理想Boost变换器为控制对象,提出一种PWM复合控制策略.应用补偿策略设计了非理想Boost变换器的前馈跟踪器,在此基础上引入了电流P型调节器和电压PID调节器,构成最终的PWM控制器.仿真和实验均表明,该控制策略不仅有效解决了非理想Boost变换器寄生损耗精确补偿的问题,而且提高了Boost变换器输出电压在大信号扰动下的动态响应.

In order to improve the control performance of practical boost converter as the large signal disturbance occurs, takes non-ideal boost converter which running in CCM as the control object, a complex PWM control strategy of duty cycle is proposed in this paper. Both Simulation and test results indicate that the control strategy can not only resolve the problem that how to compensate the parasitical waste exactly of non-ideal boost converter effectively, but also improve the dynamic response of output voltage when the large signal disturbance occurs.
