This paper presents the appliion of Silicon Carbide (SiC) devices in a high-frequency LLC resonant DC/DC converter. With high switching frequencies, the leakage inductance of the LLC transformer can be used as the resonant inductor, resulting in 50% reduction in volume and weight, and 30% decrease in power loss of the magnetic components at 500kHz and 6.6kW/400V output.
