DC-DC Converter Troubleshooting Guide: 6 Common Faults

Abstract DC-DC converters and voltage regulators are the workhorses of PV-storage-charging systems, yet most field faults in these systems trace back to six repeatable causes: input overvoltage, over-temperature and derating, output voltage drift, communication loss, insulation breakdown in humid environments, and nuisance protection trips. This guide explains each failure mode, its root cause, the engineering […]
Bidirectional DC-DC Converter Topologies for BESS — Isolated vs Non-Isolated, LLC, DAB Comparison

Abstract The bidirectional DC-DC converter sits between the battery stack and the DC link in a battery energy storage system (BESS), and its topology choice directly determines system efficiency, cost, footprint, and reliability. According to the International Energy Agency, global battery storage deployment reached 108 GW in 2025, a 40% year-over-year increase, with LFP chemistry […]
