This reference design is a 3.6kW, single-phase, totem-pole bridgeless power factor correction (PFC) converter targeting modular hardware system common redundant power supply (M-CRPS) servers. The PFC operates at continuous conduction mode (CCM) at AC peak where inductor current is high, and operates at triangular conduction mode (TCM) with zero voltage switching (ZVS) at AC low area where the inductor current is low, achieving both high efficiency and high power density. The power stage is followed by a baby boost converter, which helps to greatly reduce the size of the bulk capacitor. This design also includes e-meter functionality with 0.5% accuracy using AMC1306 as a current sensing device, eliminating the need for external power metering ICs. An alternative low-cost current sensing option using TMCS1133 is also provided in this design. This design works with the LMG3427R30 gallium nitride (GaN) device, which has an integrated zero-current detection (ZCD) circuit for TCM control. The F28003x C2000™ real-time microcontroller is used for all the advanced controls including PFC control and e-metering.
