Abstract

Decades of research have seen single-phase boost-type PWM converters be employed as front-end PFC rectifiers in commercial power supplies. The benefits of employing this technology to comply with power quality standards while assuring high efficiency and low volume and weight have been observed. However, this work shows that further efforts can be driven into new topologies. In this context, a new topology is introduced, which is able to double the frequency present in the input and output passive components and, thus, working as a full-bridge converter while employing only one additional controlled switch. Furthermore, the switches are utilized during, both, negative and positive mains half-cycles. The theoretical analysis of the topology as well as its use in a PFC application are performed and experimental verification is presented in a 1 kWprototype employing a current self-control strategy.
