Due to its simplicity, low voltage stress, high reliability, low switch and inductor losses, and small inductor size, the non-inverting buck-boost chopper has found a lot of attentions in applications where it is necessary to step-up or stepdown...

This paper introduces a novel single-phase buck-boost -non--inverting variable-frequency AC-AC converter that offers a higher efficiency compared to the competitors. This converter utilizes a lower number of semiconductors. A simple and flexible...

Two new power factor correction (PFC) rectifiers with the voltage buck-boost capability are proposed in this paper, called as Ferdowsi rectifiers, abbreviated as FRs. The proposed rectifiers employ a reduced number of semiconductors compared...

This paper presents a wide range gain buck-boost type PFC rectifier based on the conventional buck-boost DC-DC converter. This novel rectifier is fed by a buck-type Z-source network at the DC side with the help of an inductor smoothing the AC side...

Abstract – In this paper, a novel structure for a high gain
single-switch buck-boost converter with continuous input and
output power suitable for renewable energies connected to the
distribution grid is proposed and illustrated. Unlike...
