Modified Double-Dual-Boost High-Conversion-Ratio DC–DC Converter With Common Ground and Low-Side Gate Driving

This letter proposes a modified double-dual-boost (DDB) high-conversion-ratio dc–dc converter. The proposed converter is derived from the existing DDB converter by a simple yet effective circuit modification and inherits all the advantages of the existing DDB converter. In addition, the input and output can share a common ground due to the circuit modification, enabling the use of low-side gate dr...
