| Abstract: | Current-controlled pulse width modulated voltage
source inverters are most widely used in high performance AC
drive systems, because they provides high dynamic response. This
paper presents a comparative study between the hysteresis and
delta modulated current controllers for three-phase voltage
source inverter. The hysteresis controller provides excellent
dynamic performance because it acts quickly. The integrator in
the delta modulated PWM inverters acts as a low-pass filter for
harmonics. Delta modulation technique have ability to optimize
(harmonic minimization) pulse width modulated (PWM) inverter
waveforms on-line without conventional optimization processes,
like selective harmonic elimination or harmonic weighting
techniques. A comparison has been made in terms of THD level at
the three-phase load current, current error minimization and
switching frequency. The simulation study has been carried out
with the help of MATLAB Simulink environment and the
performance ... |
