Analytical Conduction Loss Calculation of a MOSFET Three-Phase Inverter Accounting for the Reverse Conduction and the Blanking Time

The reverse conduction capability of MOSFETs is beneficial for the efficiency a three-phase inverter. In this article, analytical expressions in closed form are presented which allow to quickly evaluate losses, considering effect conduction, and blanking time both sinusoidal pulsewidth modulation operation with without third harmonic injection. losses silicon carbide MOSFET inverter suitable traction applications estimated proposed method show good agreement about 98.5% measurements, performed calorimetric setup.
