N2 - In AC/DC front end applications, bridgeless power factor correction (PFC) rectifier is popular for its small number of components and low conduction losses, with the use of Gallium Nitride (GaN) devices to eliminate reverse recovery and boost switching frequency. In order to further reduce the inductor volume and improve power density, this paper proposes a novel control scheme which combines unipolar double-frequency PWM scheme with critical mode (CRM) operation for GaN-based full-bridge single-phase PFC. With the proposed control scheme, the equivalent switching frequency is doubled with both legs of the full-bridge PFC switching at high frequency, while CRM operation is maintained to achieve zero voltage switching (ZVS). Implementation of the digital-based control is also detailed. Finally, the effectiveness of the proposed control scheme is validated by a GaN-based full-bridge PFC prototype.
