Abstract

Abstract

Background
Series resonant capacitor charging power supply is widely used in the field of pulse power due to its high efficiency, high power density, and short-circuit resistance. However, its traditional PFM constant current charging control method leads to significant charging losses and reduced efficiency, which is particularly prominent in the early stages of charging.
Purpose
A multimodal hybrid constant-current charging control strategy is proposed to enhance both the charging efficiency and input power utilization.
Methods
This strategy achieves smooth transitions of charging voltage while reducing charging losses and improving efficiency through collaborative control of half-bridge mode (early charging stage), hybrid mode (mid charging stage), and full-bridge mode (late charging stage). In addition, the conversion of working modes is achieved by multiplexing power devices, which not only meets the requirements of high-voltage charging but also reduces system costs.
Results
Based on this approach, a 650 V/1 A charging power supply prototype has been designed and built. Experimental results demonstrate that, compared to conventional PFM control, the proposed strategy significantly improves overall charging efficiency, achieving a maximum efficiency of 96.4%.
Conclusions
This method not only provides an effective solution for capacitor energy storage charging systems with high efficiency and low cost, but its modal switching mechanism is also transferable to the design of other resonant converters, demonstrating broad engineering applicability.
