Dynamic characteristics of the digitally controlled DC-DC converter

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.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
