Abstract :
A modeling technique for the discrete time domain analysis of power electronics and drive systems is discussed. A discrete model for a converter-fed DC motor drive system has been developed and simulated using this technique. All system components, including the DC machine and power converter, are modeled in a discrete manner as a network of transmission line sections with the same characteristics as the drive system. The technique isolates the nonlinearity due to the devices´ switching action from the system equation and enables a constant system matrix to be used irrespective of the switching state of the power circuit. The algorithm developed provides an exact solution to the discrete model and is easily implemented on desktop computers
