A Current Control One Leg Strategy in Single Phase Five-Level Inverter with Voltage Input Balancer for on-Grid Application

Technological Developments continue to increase, this can be seen by the increasing number of electronic equipment used in daily needs, one of which is in the science of Electrical Energy conversion, namely the 5-Level Inverter. A 5-stage Inverter is a Voltage changer that can convert On-Grid DC electricity into AC electricity. Many people have done research to get a Sinusoidal 5-Level Inverter output voltage and current waveform this is done using Harmonics elimination technique. Harmonic elimination technique is a 5-Level Inverter signal processing technique for maximum switching patterns in order to obtain a Sinusodal output waveform and a minimum THD value with a combination of the STM32F407 Microcontroller control signal generator circuit and the MOSFET Driver circuit, this 5-Level Inverter is expected to have a high output waveform. Sinusoidal. In this experiment, the testers conducted experiments with the software, namely PSIM software and made real tools, and the results were that this multilevel inverter was able to produce current and output voltage with a THD of 4.07%.
