Abstract :
The dynamic characteristics of the digitally controlled DC-DC converter are analyzed both theoretically and experimentally. The stability condition and the indicial response for the step changes of the input voltage and the load are defined as a function of the circuit parameters and variables of the digital control circuit and the power stage. The optimal proportional-integral-derivative (PID) coefficients of the digital control circuit are examined
