The following aspects of good power electronics design were considered: xx The available literature indicates that conventional IGBT gate-driver circuits are appropriate for SiC MOSFETs (Safari et al.; Yu et al., 2002). Therefore, it was important to determine any optimization necessary to use a standard Si-based IGBT gate drive with the chosen SiC MOSFETs. xx To design the most compact gate-driver power supply to meet the volume objectives, determine the gate-driver power required for the SiC MOSFETs. xx Determine the feasibility of a 300-μF ceramic dc-link capacitor, which dictated volume (packaging size) and temperature requirements. xx Determine the minimum number of SiC MOSFETs and diode dies necessary to carry the inverter's rated current to minimize the power module volume. The completed breadboard inverter is shown in Figure 11. 30-kW SiC Motor Drive Inverter Another example of SiC applications is a 30-kW SiCdevice-based motor drive inverter. For this, a breadboard inverter was constructed to gain knowledge of the SiC metal-oxide-semiconductor field-effect transistors (MOSFETs) necessary to synthesize the final inverter design. 40 I E E E E l e c t r i f i cati o n M agaz ine / March 2016 Dual-Voltage ISG concept and architecture Evaluation Toward the process of greater electrification in the military, the use of an integrated starter alternator was considered important for achieving better efficiency and
