Abstract

A new computer-aided analysis technique for switching power regulators is proposed. The methodology is based on piecewise quadratic formulation of reactive element state variables with progressive analysis of switches' operation. The prominent features of this method include 1) its simplicity in not requiring any complicated mathematical calculation, such as solving Laplace-transformed equations and differential formulas, 2) its generality in determining valid topological configuration without prior understanding of the circuit operation, 3) its directness in calculating switching instants, 4) its consideration of parasitic elements. An example of a practical switch mode buck regulator with overcurrent protection and maximum duty-cycle control is illustrated. The simulated results are favorably compared with the waveforms obtained by other available literature.
