Application of semianalytical recursive convolution algorithms for large-signal time-domain simulation of switch-mode power converters

A new method of large-signal time domain simulation of switch-mode power circuits is presented. The method is based on a family of semianalytical recursive algorithms (SARA) of convolution. A general simulation method and examples of simulation results for buck and boost DC-DC converters are given. Because of absolute stability, high accuracy, low numerical complexity, and high speed, SARA algorithms seem to be a very convenient tool for simulation of switch-mode circuits.
