| Abstract |
A new modified trapezoidal modulating signal for
pulse width modulation (PWM) inverter suitable for the
Permanent Magnet synchronous motor (PMSM) drive is
proposed in this paper. A new modulating signal for the PMSM
drive is determined by the condition of reducing torque ripple of
the motor with various electromotive force (EMF). Proposed
modulating signal is able to decrease the torque ripple even if
the motor has sinusoidal EMF or non-sinusoidal EMF. By
using the proposed modulating signal, the system reduced the
torque ripple as well as achieving the effective utilization of the
DC supply voltage for the inverter. Many improvements are
accomplished by the PWM strategy adapting the modified
trapezoidal modulating signal without a change in hardware. |
