Preliminary study for implementation of hysteresis modulator using TI's TM320F28377D dual core DSP for IM drive

Hysteresis modulator is one of modulation techniques widely used in motor drives, acting as current controlled source. Hysteresis modulator needs to be implemented in analog circuits so that it is to maintain measured phase current with a certain tolerance of the desired phase current through fast sampling frequency. Because of development of semiconductor technology, new dual core DSP processor has been launched by Texas Instrument. This processor samples measured phase currents as fast as its analog circuits do. Thus in this work, preliminary study of new Hysteresis modulator is carried out using TMS320F28377D dual core DSP microcontroller.
