Level-Shifted Carrier-Based Pulse-Width Modulation (PWM) techniques for cascaded H-bridge (CHB) multilevel inverters are simple and easy to implement, but cause severe power imbalance between modules, leading to device stress and failure. Carrier-Reassignment PWM (CRPWM) techniques are a computationally simple way to achieve near-perfect power balance within a fundamental cycle. Third harmonic injection improves DC bus utilization, increases voltage levels, and reduces total harmonic distortion (THD). This paper demonstrates the superior performance of Type-A CRPWM in a three-phase grid-connected CHB inverter in closed-loop current control mode.

A novel low-leakage pulse transformer (PT) for a magnetically coupled Gate Drive Circuit (GDC) to drive multiple isolated devices is proposed.
The leakage- and self-inductances of the proposed transformer are computed using Finite Element Method (FEM) simulations and validated.
The performance of the GDC with the proposed PT is verified by driving parallel connected SiC MOSFETs for a high-speed offline induction cap sealing controller.
