N2 - An active balancing technique for the direct voltage control of flying-capacitors within a hybrid multilevel inverter is explored and experimentally verified in this paper. This method employs a set of logical variables that are derived from voltage and current measurements obtained from the floating-capacitors and inverter's ac stage, respectively. The ultimate logic-equations take the redundant switching states for each voltage-level of the adopted pulse-width-modulator into consideration, and feature prominent advantages such as a fixed-switching frequency, super fast execution-time, and ease of implementation for the industrial applications of multilevel inverters. The introduced technique is exploited for an active voltage control of a 7-level hybrid inverter which is realized from a cascaded connection of ANPC topology and two H-bridge modules. The provided experimental results validate the logic-equations and its cost-function elimination basis and optimization-free approach.
