A Converter with DSC for Speed Control of an AC Motor

摘要

The paper presents a system dedicated forspeed control with a DSC Digital Signal Controllerisolated but integrated for direct optoelectroniccommands to the DC/AC converter. The controlmethodology is dedicated to a variable load, this beingthe Permanent Magnet Synchronous Motor PMSMengine. The power block is flexible and can acceptvarious switching devices for synthesis of the motor'ssinewave currents, thus extending the applicativerange is possible. The experimental system is suitablefor a small PMSM motor used in the development ofapplication software.
