Thus the master PWM signal is generated by comparing the analog PI output Vctrl and
a triangular wave Vtriang at switching frequency. Finally, an interleaving operation is
performed and three 120° phase-shifted PWM signals (180° for two channels only) drive the
three power switches.
Moreover, the digital section includes the input voltage and load feed-forward for fast
transient response when the main voltage changes suddenly or a load step current occurs,
preventing large over or undervoltage on the output capacitor Cout.
