A High-Efficiency 4-Phase Series-Parallel Resonant Switched-Capacitor 48-to-3 V DC-DC Converter

Resonant switch-capacitor (ReSC) is a type of hybrid switched-capacitor (HSC) which utilizes both inductor and capacitor, bearing the potential to overpower conventional switched-capacitor (SC) and magnetic-based converters. This work introduces a novel four-phase series-parallel resonant switch-capacitor (ReSC) DC-DC converter topology, which...

Revisiting the Partial Power Processing Concept: Case Study of a 5-kW 99.11% Efficient Flyback Converter-Based Battery Charger

This article proposes an analytical methodology to evaluate the performance of the main partial power processing (PPP) architectures in terms of the improvements in the system's conversion efficiency. This analysis considers the influence of the system's voltage gain, the auxiliary dc/dc converter's efficiency, and the possibility of...

Highly Compact Partial Power Converter for a Highly Efficient PV-BESS Stacked Generation System

The inherently intermittent nature of photovoltaic (PV) energy has brought increasing interest towards the integration between PV sources and Battery Energy Storage Systems (BESS). In this paper, a Series Partial Power Processing (PPP) converter based on Capacitive Power Transfer (CPT) is proposed to integrate PV and BESS in a grid-connected...
