N2 - This paper presents a fair comparison between SiC-based 2-level inverter and 3-level flying capacitor multilevel (FCM) PWM inverter considering thermal variation effects on losses. A general block diagram is presented in detail which is applicable in any software to provide the loss analysis with high accuracy. Having the same heatsink and the same THD and FFT at the output stage, the 3-level FCM inverter can generate 30% higher output power with almost the same total costs. Indeed, both inverters have almost similar power losses and efficiency in the considered conditions.
