摘　　要：提出基于单周控制的单相三电平电力有源滤波器(APF)矢量模式,该模式能够使得单相APF一个桥臂工作于高频开关状态,另一个桥臂工作于工频开关状态,进而有效减少开关损耗。分析了单相APF的工作原理,在充分考虑直流侧电容电压均衡控制的基础上,提出了5种单相三电平APF单周控制矢量模式,并详细推导了各种矢量模式的控制目标方程。仿真结果表明5种矢量模式能够有效补偿无功和谐波,且效果较好,从而验证了5种矢量模式的有效性和可行性。A vector mode of one-cycle control for single-phase three-level APF is proposed, which can effectively reduce the switching losses by making one leg of single-phase APF work in a high-frequency switching state and the other work in frequency switching state. The working principle of single-phase APF is analyzed. Based on the fully considering of equalization control for the DC side capacitor voltage, five vector modes of one-cycle control for single-phase three-level APF are proposed and their control objectives equations are derived. Simulative results show that the five vector modes of one-cycle control are able to compensate the reactive and harmonic current effectively, which verifies its validity and feasibility.
