Design and implementation of a cycloconverter for variable-frequency AC signal generation

Design and implementation of a cycloconverter for variable-frequency AC signal generation. The system converts a fixed-frequency AC input into output waveforms with different frequencies through the controlled switching of power semiconductor devices. The project involved the design and implementation of the power circuit, switching control, waveform generation, and experimental evaluation of the resulting AC output signals at different operating frequencies.

Hardware Implementation and Experimental Results

PCB Design

PCB layout developed for the cycloconverter control and switching circuitry, integrating the connections required for the power semiconductor devices and control signals.

Experimental Setup

Laboratory implementation of the cycloconverter, integrating the control platform, switching circuitry, power stage, and AC supply for experimental validation.

Variable-Frequency Output Waveform

Oscilloscope measurement of the cycloconverter output during experimental operation. The obtained waveform demonstrates the generation of an AC signal with a frequency different from the input supply through controlled semiconductor switching.

Experimental Demonstration

Demonstration of the complete cycloconverter prototype during laboratory testing, showing the implemented hardware and variable-frequency AC output operation.
