Step-up converter with high voltage gain employing three-state switching cell and voltage multiplier

2008 IEEE Power Electronics Specialists Conference, 2008
This work proposes a new non-isolated DC-DC converter with high voltage gain using a three-state switching cell and voltage multiplier stages based on capacitors. The value of the gain can be modified depending on the requirements of the application by means of the number of multiplier stages and the duty cycle.
