Active Voltage Balancing Control of 9‐Level Multicell‐Based A‐NPC Inverters

open access: yesIET Power Electronics, Volume 19, Issue 1, January/December 2026.
We present a optimization‐free PWM control for single‐phase 9‐level FC A‐NPC inverters that converts measured current and capacitor voltages into logic equations to both balance FC voltages and generate the commanded levels. By removing objective functions/optimizers, it enables fast, simple implementation, with experiments showing robust performance ...
