摘　　要：探测器的能源供给离不开DC-DC变换器,先进的控制方法能提高工作效率。预测电流模式控制相比于传统的PI控制具有动态响应快、易于进行过流保护等优点,因此被广泛应用到电力电子控制领域。由于控制回路的问题,不能通过计算开环增益的方式对负载波动与输出电压变化的闭环传递函数进行有效地设计。因此,提出了一种在不加前馈控制的情况下,基于预测电流模式控制四开关Buck-Boost(four-switch Buck-Boost,FSBB)变换器补偿器的设计方案,该方法能提升负载动态响应,通过实验数据,证明了该方法的有效性。The energy supply of the detector is inseparable from the DC-DC converter,and advanced control methods can improve their operational efficiency.Predictive current mode control(PCMC)has several advantages over traditional PI control,such as fast dynamic response and ease of overcurrent protection.Therefore,it is widely used in the field of power electronic control.Due to issues with the control loop,it is not effective to design the closed-loop transfer function for load fluctuations and output voltage changes by calculating the open-loop gain.Therefore,a design scheme was presented for compensators of four-switch Buck-Boost(FSBB)converter based on predictive current mode control without feedforward control.This method could improve the dynamic response of the load.Through experimental data,the effectiveness of this method is demonstrated.
