Abstract
A theoretical study of a conventional boost converter is presented. Based on the real behavior of the components, two models of the boost converter are introduced: one dealing only with losses through inductor and capacitor and another taking into account switching losses in addition to resistive ones. From these two models, the detailed analytical expressions of both voltage gain factor and conversion efficiency are established taking into account the losses through parasitic resistances and switching losses. The behavior of the converter is then analyzed for each model by simulation for the voltage gain factor and the conversion efficiency.
Highlights
The demand for clean energy sources is actively growing leading to the development of new or alternative energy technologies
When the duty cycle is increasing the losses in the series resistance of the inductor increase to a threshold from which the losses are so important that the voltage gain factor begin decreasing for duty cycle approaching unity
We have presented in this paper a detailed theoretical study of a conventional boost converter
Summary
The demand for clean energy sources is actively growing leading to the development of new or alternative energy technologies. It is well know that its performance is limited due to higher on state resistance leading to more conduction losses in the switch, losses in the inductor series resistance and the ESR of the output capacitor [21] [22] [23] [24] These disadvantages are the major limitation of the use of that type of converter. A third category used mixed loss model that are able to synthetically and analytically calculate and analyze the component losses and system losses as functions of voltages, power, switching frequency, operating temperature of the heatsink on the semiconductors and so on These studies were not carried out on the basic boost converter but on some, more sophisticated structure [28] [29]. Simulations are performed in order to exhibit the effects of the different losses and to quantify these losses compared to the ideal model
