| Abstract | This paper discusses the design and simulation of Slope compensated Current mode Controlled Boost converter. A boost converter steps up a source voltage to a higher, regulated voltage. The current mode control strategy is discussed in this paper wherein the peak inductor current is sensed and used to control the duty ratio of the switches such that the output voltage is regulated within the specified tolerance band. Simulation studies have been carried out on a 7.5 watt boost converter designed with its power circuit and IC UC 3844 is modelled to implement the current mode control of output voltage maintained at 30V irrespective of the fluctuations in input voltage. An instability is observed at duty ratio’s nearing 0.5 resulting in sub harmonic oscillations. This issue is addressed by proper slope compensation. The entire circuit is designed and modelled using the power electronic software PSIM ©. |
