PMP23630 30 kW AI-Optimized Server PSU

This reference design is a two-stage, high-efficiency, 30kW power supply with a high voltage DC (HVDC) output. The first stage is a three-level flying capacitor PFC converter with a three-phase input source implemented with a TMS320F28P650DK high performance MCU. This topology is selected due to a frequency doubling effect resulting in smaller and higher efficiency inductors. The PFC is followed by two Δ-Δ connected three phase LLC converters that enable reduced RMS currents.
