Abstract

An active current waveshaping/control technique with continuous conduction of input current and suitable for single-phase switch-mode rectifiers (SMRs) is proposed. The nature of input current is similar to that of bang-bang hysteresis current control. The technique does not require a reference hysteresis window. Current control is achieved with constant switching frequency for a given load current. The switching frequency varies inversely with the load current, but is known and predecided. Simulated performance results and selected experimental results are provided
