Triple boost switched capacitor multilevel inverter (TB‐SCMLI) with reduced components and self‐voltage balance

IET Power Electronics, EarlyView., 2023
The proposed TB‐SCMLI is able to provide seven levels of output voltage by balancing the voltage of two capacitors with the given control logic. The various SCMLIs are evaluated to determine the contribution of the suggested TB‐SCMLI topology's merits and downsides.

Low‐power pulse width modulation (PWM) for high‐frequency DC–DC converters [PDF]

Electronics Letters, 2018
A low‐power pulse width modulation (PWM) control circuit for high‐frequency switching direct current (DC)–DC converters based on a one‐shot circuit is proposed. The proposed PWM control circuit eliminates the use of a high‐power comparator and ramp generator that is conventionally used to generate the PWM waveform.

Harmonic elimination of a fifteen‐level inverter with reduced number of switches using genetic algorithm

IET Power Electronics, EarlyView., 2023
This article presents a Fifteen‐level inverter topology that has a lesser number of switches (12) and can accommodate isolated DC sources. The total harmonic elimination (THD) of the proposed topology using genetic algorithm is within the IEEE 519 standards. Further, the fifteen‐level inverter is implemented in Hardware and firing pulses were generated
