IGBT to SiC MOSFET: Evaluating TCO and Miniaturization

The key criterion for deciding to switch from IGBT to SiC is not a device-level cost comparison, but rather how SiC-enabled downsizing of cooling systems and passive components changes the overall system BOM cost and product specifications. This article organizes application-specific decision frameworks and hybrid SiC as an intermediate solution.

EV SiC Inverters: Loss Calculation and Range Improvement

A 1% increase in conversion efficiency for EV inverters translates to a difference of several kilometers in driving range; when design engineers face the challenge of improving real-world efficiency beyond catalog values, the first question they encounter is "which losses to calculate and how." Without correctly decomposing the loss breakdown, SiC may not yield the expected efficiency improvements.

Industrial Inverters: SiC MOSFET Reliability Evaluation

When considering SiC MOSFET adoption in industrial inverter design, the focus often falls on loss and switching speed. However, a more understated and fundamental question that frequently becomes a practical concern in the field is the device's survivability during load short circuits, as the nature of applications differs between EVs and industrial equipment, where inverters are operational.
