The project is a 3.6kW bitcoin miner power supply with input 90-264Vacand output 12V300A. SiC-based totem-pole PFC and interleaved parallelsynchronous rectifier LLC topology were selected for system design. Thetotem pole PFC achieve extremely high efficiency (peak up to 99%) andthe interleaved synchronous LLC reduce output current ripple from 48%to 12% which greatly reducing output capacitor stress.
This reference design provides a low-cost server power solution. Thesystem is designed with PFC and synchronous rectifier LLC topologyusing a single Spintrol ARM4 MCU SPC1168 to control both the PFCand LLC. This solution achieves the requirements of platinumefficiency and standby power consumption standard, meets the iTHDdynamic and current sharing design requirements of full load range.which is a highly completed server power reference solution.
