Increases in the occurrence of nonlinear loads have resulted in the need to reduce or minimize the levels of harmonic currents being injected into the power supply. As a consequence, active current waveshaping and pulse-width modulation have now replaced conventional phase-controlled and diode bridge rectifiers in many applications. In this paper, mathematical models are developed for the power circuits of analog controlled single-phase and three-phase voltage source converters, and then used to analyse the performance of current- and voltage-control loops for the converters. Analytical expressions are derived for the gains and time constants of the current and voltage controllers, and it is shown that the bandwidth of the current-loop is a function of the switching frequency, and that of the voltage-loop is a function of the DC-busbar capacitance and the voltage filter cut-off frequency. To illustrate the application of the models, simulation results are presented from investigations into the control of a 5 kW single-phase voltage-source converter and a 100 kW three-phase boost converter.
