Double Dual High Step-Up Power Converter with Reduced Stored Energy
Abstract
:1. Introduction
- A new dual-switch high step-up power converter is proposed. It is identified as the “Double Dual Super Boost”, featuring high step-up voltage gain;
- When compared to the conventional boost and HSU power converters, its cumulative stored energy over its inductors is significantly less;
- Lastly, the DDSB power converter outperforms the conventional boost and HSU power converters featuring significantly less voltage stress over the active switches;
