Hybrid Modulation for Reduced Switches AC-AC Multi Frequency Converter
International Research Journal on Advanced Science Hub,
2022, Volume 4, Issue 05, Pages 134-142
This paper presents the Hybrid Modulation Technique for single phase AC-AC multi-Frequency converter to overcome the local square wave overshoot in out- put waveform which are responsible for harmonics content in converter and to get better smooth voltage waveform. And also, by using SPWM (Sinusoidal Pulse Width Modulation) and TPWM (Trapezoidal Pulse Width Modulation) a comparative analysis is done; it shows how converters behave with different modulation technique. The detail study of converter and modulation techniques are done here with including operation, block diagram and mathematical cal- culations. All the studies and experimental operation are performed by using MATLAB Simulink model simulation and the switch is used for converter is MOSFET
