浅析高压变频器功率单元的技术原理及应用

Analysis of the Technical Principle and Application of High Voltage Inverter Power Unit

现在的工业中运用高压变频器的地方随处可见;随着全控型电力电子器件的出现,交-直-交PWM型高压变频器以其谐波小,稳定性好迅速占领市场。而交-直-交变频器普遍采用单元级联式多电平变频器。

Nowadays, the high-voltage inverters are widely used in industry. With the emergence of fully-controlled power electronics,AC-DC-AC PWM high-voltage inverters dominate the market with their small harmonics and good stability. The AC-DC-AC frequency converters commonly use cell cascade multilevel inverters.
