I consolidated our benches onto a 48 V, 3 kW DC bus with point-of-load bucks and measured a 5.2% end-to-end efficiency gain at about 1.6 kW, plus 7°C cooler PSU heat sinks. What design tweaks move the needle for you — LLC front end vs interleaved PFC+half-bridge, remote sense strategy, or conductor sizing to hold <=2% drop over 10 m without failing EMI limits?
