Abstract
Control of phase currents in a three-phase voltage source inverter bridge is important for electric drives and unity power factor converters. To reduce equipment costs and overcome unequal sensor errors, the use of a single DC link current sensor is important. A new technique is described which uses redundant bridge switching states to allow current control with a DC link current sensor
