Abstract

Ramptime current control is a new robust technique for directly controlling the inductor current in switched power converters. It is largely invariant with respect to circuit parameters and system voltages. Ramptime is a sliding mode method producing zero average current error (ZACE) in each switching period with a controlled switching frequency band. The converter transient response, ripple current and switching frequency band are discussed. Simulation and experimental results showing negligible low order harmonics are presented for a single phase AC-DC power converter
