Abstract :
The basic principle of operation of a novel three-phase two-switch unity power factor flyback rectifier is analyzed and a system control concept is proposed. The stresses on the power components are calculated in an analytical form and used for designing a converter with an input voltage range of 480V±10% and 24V/50A DC output The theoretical considerations are verified by an experimental analysis of a laboratory prototype of the system
