Abstract
This paper presents the optimal design of a wide-input range, dual-output 10 W isolated active-clamp flyback (ACF) gate-drive power supply (GDPS) for high-temperature automotive applications. Detailed analysis and comparison between Critical Conduction Mode (CRM) and Continuous Conduction Mode (CCM) are provided to select the operating mode. A printed-circuit-board-embedded (PCB-embedded) transformer is carefully designed and it significantly improves the power density of the power supply. A 10 W, GaN-based converter prototype switching at 1MHz has been developed to demonstrate the attained power density (53.2 W/in3), peak efficiency (89.7%), input voltage range (8.5 V to 28 V), maximum operating ambient temperature (105 °C at 8.5 V and 115°C at 28 V), and transformer input-output capacitance (9.7 pF).
