With the emergence of Wide Bandgap (WBG) semiconductors, power electronics are experiencing a renaissance. Many design limitations, such as switching frequency, thermal ruggedness and voltage capability of silicon based power devices are being pushed to new limits with Silicon Carbide (SiC) and Gallium Nitride (GaN) based electronics.
In order to truly make use of this extended operation range, traditional topologies have to be re-imagined. To switch at higher frequencies, for example, new passives are required; using the extended thermal operation point needs a redesign of the cooling and layout of the PCB, this could lead to extensive saving of material costs. The improved switching efficiency, and reduced die footprint, despite blocking voltage capabilities beyond 1200 V, in combination with ultra-low inductive PCB design can greatly improve switching losses.
This paper presents the approach and design considerations needed to turn traditional topologies, such as a quasi-resonant flyback, into WBG optimized systems which can make use of the various added benefits provided by current prototype of ON Semiconductors SiC power MOSFET. The investigations start with a comparison of SiC based power transistors to best in class available 1700 V Silicon MOSFETs, within a non WBG optimized system. Applying a new generation of ON Semiconductor gate drivers, in combination with partnered passives developers we demonstrate how switching frequencies beyond 300 kHz are realizable in high power applications, when using a WBG optimized design and SiC power MOSFETs. To finish the work a functioning demonstrator for a variable range quasi-resonant flyback based on 1700 V SiC MOSFETs is shown and characterized.
