4 kW analogue bridgeless totem-pole PFC evaluation board

For this evaluation board, the PFC circuit has been implemented on a 4-layer PCB, with 2 oz copper for the outer layers and 1.5 oz copper for the inner layers. GAN039-650NTB devices by Nexperia are used for both the fast and slow switching legs. The inductor is made of a High Flux core with the inductance of 480 μH and a DC resistance of 0.025 Ω, designed to operate at 65 kHz. A simple 4 A rated high/low side driver IC (Si8273) with 0 V and 12 V as the on/off voltage levels directly drives each GaN FET. The control function is handled by a TI UCC28180 PFC controller.

Key features & benefits

By using a diode-free power GaN FET bridge with low reverse-recovery charge, very-high-efficiency single-phase AC-DC conversion is realized. In this circuit, the performance and efficiency improvement, is achieved by use of the GaN FETs in the fast-switching leg of the circuit. GaN FETs with low Qrr provide low loss hardswitching performance in this application.
