Abstract

Recent, Emergency Power Source littler by little Very important. Now, The converter is composed of a series connection of individual single phase converters. The number of the input current levels depends on the number of the individual inverters in series and their input current level. If the number of current levels is increased, smoother sinusoidal waveform can be obtained directly. In this paper discusses single-phase AC-DC converter that driven by binary combination at different transformer winding ratio by BCD code level. Also DC-AC Inverter. It has a advantage that constructs a control system simply and obtain load current of good quality without filter circuit and free from noise or isolation for lower switching frequency. This has merit that can do high power capacity. In this research, study on current type converter and inverter circuit that consist for possibility of AC-DC/DC-AC multi-level converter.
