Abstract

Nowadays world is facing energy crisis with shortage of power. Renewable energy sources are being utilized so as to overcome this situation. For the conversion of renewable energy to required power, new kinds of electronic converters are being used. A new dc-ac inverter is proposed by the operation of both boost and buck converter circuit. It is the simplified version of conventional Aalborg Inverter. Conventional Aalborg inverter has high switching frequency, which is reduced in the Simplified Aalborg Inverter. Over a period of AC cycle only one switch is under switching stress, with only one inductor working in the power loop. An additional natural soft switching part is added in the conventional aalborg inverter. Both advantages of VSI and CSI is achieved using buck and boost mode of operations. Addition of soft switching components further reduces switching losses. Simulation studies show that the simplified aalborg inverter improves the advantages.
