In frequency modulation, pulses of a fixed amplitude and duration are generated and the quadrangs value of output is adjusted by changing how often the pulses are generated. However, the current supplied to the load is discontinuous and may require smoothing or a high switching frequency to avoid undesirable effects.
Share This Page Tweet. The average output voltage can be controlled by different techniques namely:.
This vector includes the converter output voltage. In pulse-width modulation the switches are turned on quadranrs a constant chopping frequency. This value is used to convert motor speed from rpm to pu per unit.
The converter is fed by a constant DC voltage source. Integral gain The integral gain of the PI current controller.
