Beschreibung
This reference design is a GaN-based 3.6-kW single-phase continuous conduction mode (CCM) totem-pole power factor correction (PFC) converter targeting maximum power density. The power stage is followed by a baby boost converter, which helps to greatly reduce the size of the bulk capacitor. The LMG3522 top-side cooled GaN with integrated driver and protection enables higher efficiency and reduces power supply size and complexity. The F28004x or F28002x C2000 controller is used for all the advanced controls, including fast relay control, baby boost operation during AC drop-out event, reverse current flow protection and communication between PFC and house keeping controller. The PFC operates at a switching frequency of 65 kHz and achieves peak efficiency of 98.7%.
