Abstract
Power electronics consisting of a switch mode power supply with feedback control have a great number of applications, including many that require extreme environment capability, such as the aerospace and automotive industries.
Silicon carbide (SiC) is a common material in which power devices are created for use in switch mode power supplies, such as boost converters, giving those power supplies extremely high temperature capabilities. To truly realize the temperature capabilities of SiC in power supplies, an integrated SiC converter has been designed that is also high-temperature capable.
Herein, the properties of SiC integrate circuit (IC) processes are discussed and nonlinear-carrier (NLC) control is proposed as a controller topology that can work within the design challenges presented by SiC. A boost converter with an NLC controller is demonstrated in simulation with circuit blocks built entirely from SiC IC models.
