Abstract: This paper presents an on-board vehicular battery charger that integrates bidirectional AC/DC converter and DC/DC converter to achieve high power density for application in electric vehicles (EVs). The integrated charger is able to transfer electrical energy between the battery pack and the electric traction system and to function as an AC/DC battery charger. The integrated charger to...

Impedance converters have been developed as a new type of converter besides the two other existing converters: voltage-source and current source converters. The new converter has many inherent advantages which can be used for many applications such as wind power conversion system, fuel cell system or motor drive applications. Present research works are mostly focused on using Z-source network a...

This paper presents the three phase AC/DC converter drive effects on the linearity of the Torque-speed characteristics. A MATLAB/Simulink realization of the three phase AC/DC converter drive is described. The DC motor speed control is achieved by controlling the voltage applied to the armature circuit using three phase AC/DC converter drive. A comparison between the application of three phase s...

In this paper an optimal damped input filter is designed based on a Genetic Algorithm (GA) for an electrolytic capacitor-less AC-AC converter. Sufficient passive damping and minimum losses in passive damping elements, minimization of the filter output impedance at the filter cut-off frequency, minimization of the DC-link voltage and input current fluctuations, and minimization of the filter cos...

This paper discusses the design and implementation of single phase PWM inverter using 8051 microcontroller. The main features of 8051 based PWM inverter are simpler design, low cost, maximum range of voltage control and compact in size. The designed PWM inverter is tested on various AC loads like AC motor and intensity control of incandescent lamp in a closed loop environment.
