Abstract
A method for adjusting the output voltage of simultaneously switched DC converter along with the variation of load comprises: using a current sensing circuit to detect a variation of the load current of a simultaneously switched DC converter in order to generate a current sensing signal; using the signal to obtain a level voltage input to a pulse width modulation loop; and adjusting the peak-to-peak value of the output voltage according to the output voltage and the level voltage by the pulse width modulation loop in order to limit the value in a tolerable range of the load without generating excessive peak-to-peak ripples by the output voltage. Furthermore, the current sensing circuit outputs the current sensing signal in an average continuous waveform in order for the sample waveform of the sensing current to be closer to the load current, thereby achieving a more accurate voltage reduction adjustment.
