The conventional power conditioning units require a DC-DC converter followed by an inverter circuit to deliver the required power to the load. This increases the required power conversion stages, system cost, size and reduces the overall system efficiency. This paper presents a boost converter topology that provides DC-AC conversion along with voltage boosting in a single stage. The multi level differential boost converter topology consists of two boost converters connected back to back with a voltage boosting function. Multi level differential boost converter topology requires less power conversion stages and reduces the size of power conditioning units. This converter topology can be employed in uninterruptible power supplies and AC drives. With the differential boost converter topology, a ripple free pure sinusoidal wave can be obtained. The differential boost converter topology provides a multi level output along with voltage boosting by employing a single DC voltage source. The design and analysis of multi level differential boost converter have been done.
