Abstract

This paper describes a power conversion circuit conguration for three-phase boost dc-ac converter (inverter) based on the dc-dc boost converters. It naturally generates in a single stage three-phase ac voltages whose peak values are greater than the dc input voltage. This property is absent in the conventional three-phase inverter, as it inherently bucks. The proposed three-phase inverter comprises three dc-dc boost converters whose individual output voltages are modulated sinusoidally. Sliding mode controllers are designed to perform a robust control for the three boost dc-dc converters. Computer simulations and spectral analysis demonstrate the feasibility of the proposed three-phase inverter. The inverter is intended
to be used in three-phase electric drives and uninterruptible power supply (UPS) systems.
