This paper presents a new DC-AC converter which not only acts as inverter but also boosts the output voltage with respect to input. This topology is cost-effective due to reduced switch number and it is suitable for compact design. Switching strategy in this topology is similar to conventional inverter and in each half cycle, boost operation is done by one of the two boost converter. Variable duty cycle is applied for generating sinusoidal output voltage. Theoretical analysis and operation principle are presented together with simulated results to validate the proposed concepts.
