Wolfspeed’s SpeedFit is a powerful online simulator that allows designers to quickly evaluate different power conversion topologies and Silicon Carbide (SiC) devices. The platform is best utilized early in a design cycle to analyze design tradeoffs between different topologies, estimate semiconductor losses and junction temperatures, as well as identifying the best Silicon Carbide (SiC) MOSFETs and Silicon Carbide (SiC) diodes to use in a given design. This saves a great deal of time by reducing the need to sort through datasheets and calculate device losses to select an optimized device. The SpeedFit tool supports numerous power conversion topologies for DC-DC, AC-DC, and DC-AC to support a wide range of applications. This whitepaper will explore some of the topologies including newly added options and demonstrate how SpeedFit can be used to evaluate different device packages and paralleling options.
