This reference design is a 3.6-kW, automotive 400-V to 12-V unidirectional converter which converts the 200-V to 450-V DC input to 12-V,300-A maximum output. Circuit breaker is applied for overcurrent and overvoltage protection. The converter is designed with SiC MOSFETs on the high voltage side and driven by 5.7-kVRMS,reinforced isolated dual-channel gate drivers. The enhanced phase-shifted full-bridge controller implements programmable delays which ensure zero voltage switching (ZVS) over a wide range of operating conditions. It offers multiple lightload management features including burst mode and dynamic SR on and off control when transitioning in and out of discontinuous current mode (DCM) operation. The output implements synchronous rectification,which enables fast transient response and a high-loop bandwidth.
