摘　　要：由于传统方法在高频通信电源运行控制实践操作中控制效果不够明显,高频通信电源回归稳态时间较长,为此提出基于DSP的高频通信电源运行控制方法,利用DSP对高频通信电源拓扑矢量转换处理,使高频通信电源运行中的拓扑矢量均衡分配到电源拓扑结构上。设计输出电容中点平衡控制方程组,通过计算三相功率在一个电源开关周期内需要的导通时间,控制高频通信电源输出电容中点平衡,以此实现基于DSP的高频通信电源运行控制。经实验证明,应用此次设计控制方法回归稳态的时间低于传统方法,适用于高频通信电源运行控制。Because the traditional method is not obvious enough in the practical operation of high-frequency communication power supply operation control,it takes a long time for the high-frequency communication power supply to return to the steady state.Therefore,a DSP-based high-frequency communication power supply operation control method is proposed.Utilize DSP to transform the high-frequency communication power supply topology vector,so that the topological vector in the high-frequency communication power supply operation is distributed to the power supply topology structure,design the output capacitor midpoint balance control equation group,by calculating the three-phase power in a power switching cycle control the midpoint balance of the output capacitor of the highfrequency communication power supply during the turn-on time in the internal,so as to realize the operation control of the high-frequency communication power supply based on DSP.Experiments have proved that the application of this design control method takes less time to return to a steady state than the traditional method,and is suitable for highfrequency communication power supply operation control.
