Abstract :
The circuit design and structure of siggle-phase bridge voltage source inverter were presented in detail. The main experimental waveforms were given. The reasons that static error is universally bigger in siggle-phase alternating control systems and the output voltage fluctuation resulted from the load changes were analyzed. The regulator was designed with internal model principe to reduce the static error. The changes of farthest points of control object were restrained when load changes the combining the positive feedback with negative feedback.
