| 摘 要： | 介绍了一种基于DSP的二极管钳位三电平逆变电源设计．主电路前级采用推挽电路升压整流，为后级提供稳定的直流母线电压．后级采用二极管钳位三电平逆变电路，产生稳定的220V／50Hz交流电压输出．电源采用数字化控制，驱动信号由DSP计算产生．逆变器工作于恒压模式，采用电压电流双闭环PI控制策略，通过PI算法调节三电平逆变电路的驱动占空比来实现闭环控制．最后制作了1kW的样机进行验证，实验证明，方法可行，具有好的应用前景．

| Abstract: | A diode-clamped three-level inverter power supply based on DSP is introduced. A push-pull circuit is applied to main circuit forward for boost rectification,preparing stable DC voltage for after circuit. The after circuit adopted diode-clamped three-level inverter to output stable 220V/50Hz AC voltage. The power supply based on digital controller and driver signals produced by DSP. Inverter operated on constant voltage mode, using voltage- current close loop control strategy. The three- level inverter＇s duty cycle is adjusted via PI arithmetic to achieve closed-loop control. The feasibility of the design scheme is verified through a 1 kw prototype machine, proving favorable and having high practical value. |
