This paper introduces a novel simulation algorithm for closed loop frequency response analysis by Fourier Transform Method (FTM). FTM is reviewed briefly and novel analysis algorithm is described. The simulator employing this novel algorithm is developed and demonstrated for a buck converter with feedback. The simulation result is in good agreement with the experimental result.
In this paper, a novel discrete model has been proposed to simulate the controller IC UC3854. The main contributions are as followings: 1) The power stage of the Boost converter has been modeled by using the large signal approach and the loop gain of current program has been put forward; 2) The continues-time voltage control diagram has been investigated by employing equivalent power stage which contains...
This paper presents the system modeling and analysis of the single-phase current regulation module (CRM) in continuous-conduction-mode (CCM) at steady state for use in the electrical discharge machines (EDMs). Based on the equivalent model of the three-terminal PWM switching cell, the small-signal equivalent circuit models of the single-phase CRM are obtained to derive the corresponding open-loop...
