A multilayer inverter that can generate 17 distinct voltage levels has recently become available for purchase. This inverter makes use of cascaded Hbridge modules that have floating capacitors and a three-level flying capacitor inverter. In this study, a number of aspects of the inverter that has been suggested are described. One of these aspects is the inverter's capacity to maintain a voltage balance across its capacitors. The findings of the experiments are used to investigate the efficiency of the suggested converter. The algorithm that is used to balance capacitors has been evaluated to ensure that it is stable in both transient and steady-state situations. Instantaneous balancing of all of the capacitors in this circuit is possible by utilising any one of the pole voltage combination options. This architecture has a number of advantages, one of which is that it makes it possible to operate the converter in back-to-back mode, with all of the voltages being generated by a single DC link power supply. The inverter that is now being demonstrated has the capacity to support a full range of load power factors in addition to modulation indices. Even if one of the H-bridges fails, the inverter can still be used at full load; the only difference is that it will be able to produce a lower total number of levels. In this setup, both the dv/dt and the common mode voltage variation are rather little. This is because both of these measures are dependent on time.
