This evaluation board introduces a complete Infineon’s system solution for a 3 kW power supply unit (PSU) targeting the newly released OCP V3 rectifier specifications for servers and data centers.The PSU comprises a front-end AC-DC bridgeless totem pole converter followed by a back-end DC-DC isolated half-bridge LLC converter. The front-end totem pole converter provides power factor correction (PFC) and total harmonic distortion (THD). The LLC converter provides safety isolation and a tightly regulated output voltage.The measured peak efficiency of the complete PSU at 230 VAC is 97.5%, not including the internal fan, and 97.4%, including the internal fan. The overall outer dimensions of the PSU are 73.5 mm x 520 mm x 40 mm, which yields a power density in the range of 32 W/inch³ (1.95 W/cm³).
