Saber Simulation and Experimental Research on Single-phase Digital Inverter with PI Control
In order to nuke the inverter system has a better control flexibility and stronger interference immunity, an inverter based on digital control is created. This design can improve the output stability through controlling the instantaneous value of voltage loop. Meanwhile considering dynamic output performance, digital PI control is applied to the closed-loop system. A simulation and an operation are designed to confirm that. Firstly a simulation model of the single-phase digital inverter is established on Saber simulation platform to make a simulation for PI closed-loop strategy which is used in the inverter. Besides that a hardware circuit is set up to bring about the closed-loop design of single-phase digital inverter. The results of simulation and operation show that output waveform is better and this system has stronger interference immunity. It proves that single-phase digital inverter by PI control can be easily controlled. Whats more its convenient to upgrade and maintain this inverter.
