ZETA converter applied in power factor correction
Adriano Péres, Denizar Cruz Martins, Ivo Barbi · 2002
This paper presents the analysis of the ZETA converter operating in discontinuous conduction mode (DCM) for power factor correction. The main attraction of the ZETA converter is that it is a naturally isolated structure, which allows a regulated output voltage with only one power processing stage. The principle of operation, mathematical analysis, design procedure and experimental results obtained from a laboratory prototype are presented.>
