摘要：

The GaN-based critical conduction mode (CRM) totem-pole power factor correction (PFC) converter with full-line-cycle zero voltage switching (ZVS) is a promising candidate for high-efficiency front-end rectifiers. However, the input current can be degraded by line-cycle current distortion and ac line zero-crossing current spikes, and maintaining reliable ZVS control is difficult in noise-susceptible high-frequency environments. In this paper, a detailed analysis of the current distortion issues in a GaN-based CRM totem-pole PFC with digital ZVS control is provided, and effective approaches are proposed to mitigate different kinds of current distortion and ensure stable ZVS control under high-frequency operation. The proposed solutions have the advantages of straightforward implementation and do not increase the control complexity. The current distortion issues are demonstrated in two GaN-based CRM totem-pole PFC prototypes, a 1.5 kW PFC for data centers and a 100 W PFC in a 6.78 MHz wireless charging power supply for consumer electronics. The proposed methods are experimentally verified with effective mitigation of the current distortion and improvement of the converter power efficiency. © 2020 IEEE.
