Abstract: This paper deals with the design of a single phase six switch AC/AC converter for UPS application. Reduced switch-count topology is used here. This converter is designed for calculating the optimal operating point of the converter based on the design specifications in order to maximize dc bus voltage utilization. It is designed in such a way that output voltage has less THD with unity power factor. This also enhances battery charging applications and also increases the input power. There by the proposed converter has Less THD of input current and output voltage and unity power factor. The strategies have been confirmed by both simulation and experimental results obtained from the converter which used for UPS applications.
Keywords: UPS, AC/AC Converter, PWM Control, Switch Reduction, THD.

Scope of the Article: Switching and Addressing
