32 bits high performance single chip microcontroller MC68332 for the control of cycloconverter

摘要

The increasing availability of single chip low cost microcontroller has provided an inexpensive, flexible, and sophisticated means for electronic control. The use of microcontrollers rather than microprocessors to keep equipment compact, reduce the number of components and improve reliability. There is much interest in using microcontroller 32 bit MC68332 (Motorola), combining high-performance data manipulation capabilities with power peripheral subsystems, and HCMOS technology for firing and controlling of cycloconverter. The authors represent the simplified (3 phase to single phase) and effected method of control of cycloconverter phase using the microcontroller MC68332. Comparison between the experimental results and simulation results of the load voltage and current in different values of output frequency has been done. Also spectrum analysis of the harmonics of the output voltage has been represented. The inputs phase and load currents corresponding for various values of the output frequency has been represented.
