Abstract

Based on the loss-free resistor concept, a model of a network which enables ideal ACDC conversion (zero line harmonics, unity power factor, nonpulsating output DC) is derived. Such a conversion unit has a hyperbolic output characteristic, which enables it to be operated with a variety of loads, and makes it suitable to be operated as a basic building block in modular systems. This approach has been verified experimentally, by the construction of a high quality three-phase AC-DC converter, based on three flyback circuits that realised the loss-free resistors.
