摘　　要：提出了一种采用IPM大功率模块实现的高分辨率调压电源的设计方法。该方法采用粗、细调节的方式实现了高分辨率的电压调节。重点介绍了逆变方式下粗细调节部分相位一致问题。试验结果表明这种方法切实可行。A method of increasing the resolution of single-phase variable voltage AC power supply with IPM power module is proposed. The high resolution of power supply consists of thick and thin regulation parts. The way of adjusting the outputs of thick and thin regulation parts is mainly introduced. The results of experiment show that the method works well.
