EZ-GaN EZ-GaN Evaluation Board, Totem-Pole PFC Complete 1000 W Totem-Pole PFC Evaluation Board with HV GaN HEMTs and 99% Peak Efficiency The introduction of Transphorm’s 600V GaN power transistors allows unconventional circuits previously impractical to implement. The simultaneously low on-resistance and low reverse recovery charge from these 1st-generation GaN-on-Si high electron mobilty transistors (HEMTs) offer a new keystone in building a longawaited totem-pole power factor correction (PFC) circuit. In addition to excellent potential for low common-mode EMI noises, this elegant GaN-based PFC features the least number of fast power devices and offers the least resistance paths for the main current, enabling a prototype to achieve 99% efficiency. Q2 (a) S2 VO+ LB Vs A GaN HEMT totem pole PFC in CCM mode consists of a pair of fast GaN HEMTs (Q1 and Q2) operating at a high pulse-widthmodulation (PWM) frequency, as well as a pair of slow but verylow resistance MOSFETs (S1 and S2) operating at 60Hz.
