If overmodulation occurs, the output voltage of the power converter clamps to the positive or negative DC rail. In the Three-Phase Two-Level PWM Generator example, the Two-Level Controller subsystem contains a 400–V DC-link input, and a modulation index, m, of 0.8. For SPWM, the maximal...
ThePWM Generator (DC-DC)block outputs a pulse to fire the MOSFET, GTO, or IGBT switch of a one-quadrant converter (buck or boost). The duty cycle of the generator is specified by the input D. A value between 0 and 1 determines the percentage of the pulse period that the output is ...
Consequently, a time ratio regulating means functions to shift the command voltage of a command voltage generator 2, so that allotment of loss is varied between switch elements on the positive and negative bus sides thus controlling loss of the switch element and protect it against thermal ...

Timers 0 and 1 include a PWM function (PulseWidth Modulation),which can drive an external I/O signal. The PWM for timer 0and 1 have an optional dead-zone generator capability, which can be utilized tosupport a large current device. Timer 2, 3 and 4 are internal timers with no output...
;PWM generator ;argument: T = (11 + 11*(freqL0)) * t = 11*(1 + (freqL0)) * t ; Duty = (11 + 11*(dutyL0)) * t = 11*(1 + (dutyL0)) * t ; IF (dutyL0) = 0, THEN Output low level constantly ; IF (dutyL0) >= (freqL0) + 1, THEN Output High level cons...
Another possible option is to skip this PWM business altogether. You could use the same PWM generator, but sample the signal with an external circuit to create a waveform which is not modulated, and has no harmonic distortion. An example of this kind of circuit is shown below, basically an...
