Power electronic circuits comprising of AC-DC converters and DC-DC converters are Integral part of modern day electric vehicle. Batteries play a major role in a electric vehicle. Thus the selection and implementation of battery charger using DC-DC converter has important role in the development of electric vehicle. In addition to this, the existing battery chargers are without power factor correction which will affect the life and performance of the battery. So this paper presents a charging circuit for batteries used in electric vehicle with the concept of power factor correction. This paper emphasis the necessity for a boost converter for the power factor correction. Half bridge converter topology is implemented for battery charging purpose and it is simulated using MATLAB software with rectifier and boost circuit for verifying the improvement in power factor correction. The power factors and harmonic distortion obtained are presented and analysed in detailed.Keywords

The main objective of this paper is to achieve a feedback enabled multi output boost converter (MOBC) by combining power electronics and process control concepts. A multi output boost converter produces multiple outputs from a single input. It provides two or more output voltages from a single input voltage. The implementation of feedback enabled MOBC comprises of basic MOBC unit, two comparators and a PI Controller. The PI (Proportional-Integral) controller here as such controls MOBC output based on its error input obtained as a result of comparison of MOBC output and setpoint. The use of electronic PI controller contributes to better stability of output and acts as a corrective mechanism to the MOBC.Keywords

Industrial, residential and aerospace environments widely use switching mode power supplies. Switching modepower supplies need to be of small size as well as highly efficient. Hence a high switching frequency is necessary for reducing the size of the converter. But as the switching frequency increases, switching loss will also increase. This will result in gradual decrease in the efficiency of the power supplied. This paper is an attempt to study the application of fuzzy based control for DC-DC converters operating at finite switching frequency. Conventional PI method currently used for buck boost converters is compared with the fuzzy based control. Simulation results are also presented. The simulations show that the fuzzy control method has better dynamic performance.
