Abstract Totem-pole power factor correction (PFC) is widely used in EV chargers to improve the charging efficiency. A full-range ZVS control model considering ZVS margin and light load frequency limitation is proposed in this paper, full ZVS operation is realized within full voltage range. The impact of zero-current-detection (ZCD) delay on the total harmonic distortion (THD) of input current is analyzed, and a ZCD delay compensation method based on the on-line time calculation model is proposed, the full load THD is reduced by 1.4%. For the phase error of two-phase interleaving, a phase error compensation method considering the change of switching period is proposed, which improves the interleaving accuracy and the full load THD is further reduced by 0.5%. Finally, a prototype of 3-kW portable charger is built to verify the effectiveness of the proposed control strategy. The maximum efficiency of the totem-pole PFC stage is 98.8%, and the maximum charging efficiency is 96.6%. The full load THD is 2.4%, which is 1.9% lower than that before compensation.
