Effects of sliding dynamics and filippov fields in the simulation of a boost-flyback power converter with an average current control mode

摘要

In this work we have simulated and physically implemented a boost-flyback power converter with an average current control mode which presents two sliding dynamics. We have tested four applications to perform the simulations: NGSPICE, PSIM, PLECS, MATLAB/SIMULINK/SIMSCAPE. We have developed a program that detects the sliding dynamics and solves a Filippov field in order to avoid blockages and long simulation times. We compared our program with PSIM and obtained speed ups around 119 times. Finally, a discussion about pros and cons is presented.
