Abstract
This paper proposed a complex control with a various-gain controller to increase the quality of output waveform. First, the inverter is compared with the DC motor to show that the way used for a DC motor servo system can be easily applied to that of the inverter. Then, the complex control is analyzed in detail. In order to achieve low THD of the output waveform with all loads, a new kind of controller whose gain is changed according to the load current is used. Simulation and experimental result proved it.
