Pulse-code modulation (PCM) is a digital representation of an analog signal where the magnitude of the signal is sampled regularly at uniform intervals, then quantized to a series of symbols in a numeric (usually binary) code. PCM has been used in digital telephone systems and 1980s-era electronic musical keyboards over one pulse repetition period (the reciprocal of the pulse repetition rate), and then the result of this integration is held for one pulse repetition period. Since the amplitude is the same for all pulses in a PWM pulse train, any one integration gives a value that is proportional to the width of the pulse on the input the amplitude and phase dynamics in phase shift control. The published ACCS work for realistic scale liquid-fuel combustors is in control of one (main) oscillation mode using fixed amplitude of the fuel flow modulation. A single mode was controlled in our experiments and a single-mode model is considered below. This is, perhaps, the simplest. In this study, a selective harmonic elimination (SHE)-pulse-amplitude modulation method is suggested for the cascaded multilevel inverters.
