Switched capacitor based Z‐source DC–DC converter [PDF]
IET Power Electronics, 2019 This study proposes a common grounded Z‐source DC–DC converter. In comparison to conventional Z‐source converter, it converts voltage with higher voltage gain and lower voltage stress on the switch, diodes and capacitors. In addition, it needs smaller inductors in comparison to the similar converters.
