In order to use in motor drives, it is desirable to increase the
fundamental magnitude of output. Clearly, each α value yields
a different harmonics content of the trapezoidal. However, it
should be noted that the fundamental component magnitude
will also be reduced if α is selected towards 90o. Therefore, to
gain high fundamental magnitude, α should be placed nearby
0o. By eliminating a number of dominant harmonics, an output
voltage with high fundamental magnitude and low harmonic
content can be obtained. The method of trigger pulse
generation for a particular frequency is described in [11]
