A Z-Source Network Integrated Buck-Boost PFC Rectifier [PDF]
International Journal of Industrial Electronics, Control and Optimization, 2019 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 input ...

A high efficiency non-inverting multi device buck-boost DC-DC converter with reduced ripple current and wide bandwidth for fuel cell low voltage applications [PDF]
Serbian Journal of Electrical Engineering, 2018 The voltage produced by the fuel cell (FC) device is unregulated and varies from 0.4 V to 0.8 V on full load to no-load respectively. When these devices are used in low voltage applications and output voltage lies between higher and lower values of input

Comparative Study of 4-Switch Buck-Boost Controller and Regular Buck-Boost
International Journal on Advanced Science, Engineering and Information Technology, 2011 A very important characteristic that dc-dc converters require is the ability to efficiently regulate an output voltage with a wide ranging value of input voltages. A recently developed solution to this requirement is a synchronous 4-Switch Buck-Boost controller developed by Linear Technology. The Linear Technology’s LTC3780 controller chip enables the
