| 摘 要： | 介绍了采用能量控制策略的Buck—Boost直-交变换器，对该变换器的拓扑电路、工作原理以及控制策略进行分析和仿真。仿真结果显示：在相同的开关频率下，采用能量控制策略比SPWM的输出电压的谐波分量小，对电网电压波动和负载扰动无明显动态调整过程。该控制策略可应用于高性能正弦交流电压源和变频变压系统中。

| Abstract: | This paper introduces a Buck-Boost DC-AC converter based on energy control strategy. The analysis of the converter topology structure, the working principle and control strategy and simulation are included in this paper. The simulation results proved that the harmonic component of the output voltage based on energy control strategy is less than that based on SPWM control strategy and there is no regulation process when power supply network fluctuates and load changes. This control strategy can be applied to high performance sinusoidal power supply and VVVF system. |
