The Equivalent Circuits of Switched Converters for Calculating Current and Voltage Harmonics. Part 2
A procedure for constructing the equivalent circuit of a three-phase switched converter for calculating higher harmonics of current and voltage in power supply systems is presented. It is shown that the equivalent circuit comprises a source of voltage determined by the rectified current at the instant when switching occurs, a distortion e.m.f determined by the power supply voltages of all the three network phases, and three sources of current determined by the switching currents.
