Abstract :
A detailed analysis of operation and a basic design procedure for a new high-frequency (HF) resonant-converter technology with phase-shifted regulation is presented. The new HF resonant technology has a good potential to be a cost-effective solution for the voltage regulation modules (VRMs) for the next generations of microprocessor systems. The new HF resonant technology is employed in the development of a 1.8-MHz, 48-V, 130-W (0.95–1.7 V, 100A) VRM. Experimental results are provided.
