Design of Directional Converter for Electric Vehicles Using Microcontroller

This work presents the Bidirectional converter and the Atmega8 microcontroller connection for electric vehicles (EVs) applications. Mainly this project is used to convert the regenerative energy under removing accelerator condition to electrical energy. An original method for the embedded energy management is proposed. This method is used to share the energetic request of the EV between the accelerator and the battery. The microcontroller is connected with bidirectional converter which provides automatic control for regenerative energy conversion from accelerator to the Battery. The PWM control technique is used to adjust duty cycle of converters. Bidirectional dc-dc converters (BDC) has recently received a lot of attention due to the increasing need to systems with the capability of bidirectional energy transfer between batteries and the motor in the electric vehicle. Apart from traditional application, the new applications of converter include energy storage in renewable energy systems, fuel cell energy systems, hybrid electric vehicles (HEV) and uninterruptible power supplies (UPS).By using this project, we can convert regenerative energy into an electric energy and that is stored in the battery. Here, we use double carrier PWM technique for changing the duty cycle. Also it provides Constant voltage transfer between motor and battery. It consist of solar panel which is connected to the DC power supply (Battery).Due to the voltage from solar panel it change the duty cycle of bidirectional converter and the regenerative Energy conversion also gets change. Hence regenerative energy is converted as electric energy and it again stored in the battery.
