A high power and multi-outputs of AC-DC power supply design to meet 80 plus platinum and ErP requirements
In this paper, the soft-switching multi-outputs full-bridge LLC resonant converter with matrix transformer, synchronous rectifiers and DC-DC buck converter with synchronous rectifiers is proposed. The new proposed simple structure of PC power supply with LLC multi-outputs resonant converter has the features of frequency modulation operation with fixed 50% duty cycle, zero voltage switching (ZVS), low voltage stress in the active switches, high efficiency, and excellent compatibility, which can achieve 80 Plus Platinum and 2013 ErP requirements. Energy consumptions at primary side components of full-bridge LLC and half-bridge LLC resonant converter are also compared in desktop ATX PC power supply with high power applications. Finally, the new PC topology is presented, and a specific example for 1200W PC application is designed and implemented to verify its feasibility.
