Computation of averaged characteristic coefficients for elementary PWM converters
1998
In this paper, an algorithm and a program for the computation of the averaged characteristic coefficients of elementary DC-DC PWM converters (buck, boost, buck-boost), in both operating modes (continuous and discontinuous), are presented. The program is principally conceived for the element determination of the unique circuit model for a PWM converter. This circuit model with fixed topology has the same structure as well as the circuit model from the injected-absorbed-current method. But, the elements of the circuit model, that is the characteristic coefficients, are deduced from the small-signal averaged model obtained through the state-space averaging method.
