Abstract
There arc two ways in the output voltage control method in PWM inverters. One Is double loop voltage control composed of inner current control loop and outer voltage control loop.'rho other is single loop voltage control method composed of voltage control loop only. It's characteristics shows lower performance in case of high output impedance than double loop voltage control. However, in case of low output impedance, it shows good control performance in all load ranges than double loop voltage control. In this paper, the rule and the gain of single loop voltage control have been developed analytically and these were verified through computer simulation and experiment.
