High voltage gain boost converter based on three-state switching cell and voltage multipliers

2008 34th Annual Conference of IEEE Industrial Electronics, 2008
A new type of non-isolated step-up converter with high voltage gain is proposed on this work. It is suitable for applications with a high voltage gain between the input and the output stages. In this converter, the output to input voltage ratio, for a given duty cycle, can be raised by adding voltage multiplier stages of capacitors (mc).The theoretical

Transformer-less bidirectional PWM converter integrating cell voltage equalizer using voltage multiplier for series connected energy storage cells

2017 IEEE 3rd International Future Energy Electronics Conference and ECCE Asia (IFEEC 2017 - ECCE Asia), 2017
Traditional energy storage systems consisting of lithium-ion battery cells or electric double-layer capacitors (EDLCs) connected in series require a cell voltage equalizer in addition to a bidirectional PWM converter. The system is prone to complexity as two converters (i.e., the equalizer and bidirectional converter) are separately necessary.
