Applications of the generalized state-space averaging method to modelling of DC-DC power converters
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 (TM) and SimPowerSystem (TM) of SIMULINK. Beside, simulations using the proposed model reduce the simulation time by 64% as an average in comparison with the available software packages.
