6 / 40 page ![]() STNRGPF01 control architecture STNRGPF01 6/40 DocID030377 Rev 2 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. |
