Design and Implementation of IGBT Based Single Phase Multiconverter for Industrial Load Control

Multi-converter operates as cycloconverter, cycloinverter, controlled AC-DC converter, and AC voltage controller. This paper represents the design, operation, and hardware implementation of an IGBT-based multiconverter prototype. The presented single-phase multiconverter prototype has output frequencies of 10Hz, 12.5Hz, 16.67Hz, 25Hz, 50Hz, 100Hz, 150Hz, 200Hz and 0Hz with 230V load handling capability; which makes it more useable in real-life scenarios. The multiconverter circuit is modeled, analyzed, and simulated in MATLAB/Simulink. The Arduino nano microcontroller-based electronic circuit is used to generate the firing pulses. A laboratory prototype is developed to simultaneously control the rms as well as the average value of output voltage and frequency of the power supplied to the load. Experimental results are presented to validate the theoretical design, analysis, and simulation results.
