This reference design presents an extremely compact auxiliary power supply with a combined output power up to 6 W. Three different isolated bipolar output voltages are provided: +15 V / -4 V, +19 V / -4 V and +20 V / -5 V. The design is optimized for driving high-voltage SiC-MOSFET and IGBT discrete devices as well as power modules in high-power converters, and can be easily integrated in the gate driver system. The extremely low interwinding capacitance of the WE-AGDT transformers down to 7 pF helps to achieve high CMTI rating (Common-Mode Transient Immunity). This enables fast switching speeds which can yield efficiency and power density gains, as increasingly required in trending applications in e-mobility,renewable energy or industrial automation.
