摘要
详细分析了单相Boost型AC/AC交流变换器的工作原理及其控制策略。通过对输入电压的极性判断,并结合输出电压误差放大信号与三角载波的比较结果,可确定各开关管的工作状态。对单相Boost型AC/AC交流变换器进行了仿真研究,并研制了一台原理样机,仿真和试验结果验证了理论分析的正确性及控制策略的可行性。
The operation principle and control strategy of single-phase Boost type AC/AC converter were analyzed in detail. By recognizing the polarity of intput voltage and comparing the error amplification signal of output voltage with the triangular carrier, the operation state of switches are determined. In the ?aper, single-phase Boost type AC/AC converter was simulated'and a prototype was designed. The simulation and experimental results verified the correction of the theory and the feasibility of the control strategy.
