Characteristics Analysis and Design of a Resonant dc–dc Converter With ZCS and Short-Circuit Fault Current Limiting Capability
TL;DR: In this paper , a series-resonant dc-dc converter (SRC) which features zero current switching (ZCS) and open-loop control is used for providing galvanic isolation and voltage scaling, but output short-circuit (OSC) fault is a challenge for SRC because it will cause dramatically high current in the low-impedance resonant tank.

- 26 Jul 2021
TL;DR: In this article, the behavior of an uninterruptible power supply (UPS) using COTS-based equipment on a ship's power distribution system was investigated and it was found that when the frequency of the mains supply is deviated by 5 % the current at the UPS input is modulated and the maximum current is increased.
