Abstract :
Classical 3-phase inverters cannot produce AC voltage with the magnitude greater than DC input voltage. For an approach a DC-DC boost converter should be used between the DC voltage source and DC-AC converter. This solution causes high volume, weight, cost and poor efficiency. In this paper, a new topology for a three-phase boost inverter is proposed. The inverter is made of three boost converters which are able to track desired output voltages exactly. In addition, sliding mode controllers are design to perform a robust tracking control for the boost converters. Simulations are also carried out to verify the operation of the proposed three-phase inverter as well as its sliding mode controllers in different conditions.
