Abstract

The purpose of this paper is to quantify existing random noise in a pulse-width modulated (PWM) switching DC-DC boost converter. We propose a model from a different perspective. An experimental study is performed to measure and characterize random noise on system parameters of a boost converter. Experimental results show that the characteristics of random noise in the converter are Gaussian distributed. The paper uses stochastic differential equations to incorporate the random noise into system dynamics. These disturbances are modeled as a random process due to switching time uncertainties. This model can be used to quantify the stability of a converter that is directly affected by random fluctuations in realistic situations.
