Abstract:
This project presents a new single-phase to three-phase cycloconverter suitable
for driving an induction motor. Using discrete variable frequency technique, a
single-phase to three-phase modulation strategy is proposed, the output frequency
of this cycloconvertor can be up to half of the input frequency. Only six naturally
communicated thyristors are employed, so the resulting cycloconverter-motor drive
system is cheap and compact. Software in C and assembly language has been
written for real-time control. The simulation based on Matlab/Simulink is used
to predict the performance for the cycloconverter and induction motor.
