Abstract: Power converter models are time varying because of the switching action of power electronic devices. To find time-invariant models, this tutorial article presents the applications of the generalized state-space averaging method to the modelling of a zeta converter feeding a resistive load and paralleled buck converters driving a DC motor. Simulations using the proposed models with MATLAB coding agree well with the results of PSIM™ and SimPowerSystem™ of SIMULINK. Beside, simulations using the proposed model reduce the simulation time by 64% as an average in comparison with the available software packages.
