Two-phases inverter fed from single phase supply, using phase shift control circuit

This paper presents a two phases inverter fed from a single-phase supply, using only two power semi-conductors switches. The first phase is a single phase supply and the second phase shifted out the first one by 90° using the static power conditioner. The static power conditioner consists of a diode bridge and two power switches for half-bridge inverter with two capacitors in the DC link. The change in voltage magnitude of the second phase by the control in firing angle for half-bridge inverter is realized using microcontroller. Complete implementation for the design data of a static power conditioner and the control circuit using microcontroller is obtained. The control circuit is accomplished using a suitable microcontroller soft-ware program. The measured signals and computed results obtained from the theoretical analysis are matched with my results.
