P. R. Mahboob, Nithin S, and K. Vijith, “A Multi-Mode Power Converter for Electric Vehicle Charging”, in 2020 5th International Conference on Communication and Electronics Systems (ICCES), 2020.[Abstract]

A Multi-Mode Power converter (MMPC) suitable for Electric vehicle (EV) charging, with multifunctional operation in a single interleaved converter topology is proposed here. The MMPC incorporates AC - DC mode to charge the EV from the residential grid, Bidirectional DC-DC mode for internal power management and DC - AC mode for V2H operation. The interleaved topology of MMPC reduces the voltage and current ripple and performs power factor improvement during EV charging. The design and simulation results of MMPC using MATLAB Simulink are presented.

Nithin S, K. Vijith, C., R., and Dr. Sasi K. K., “Automated Dispatch of Wind Power On Microgrid For Voltage Regulation”, International Journal of Automation and Smart Technology, vol. 9, no. 3, 2019.[Abstract]

The variability of wind power generation adversely affects the grid conditions and the utilities find it challenging to accommodate variations in the injected wind power. To resolve this issue utilities impose curtailment of wind power generation. Demand side management (DSM) strategies have gained popularity among utilities in recent years. An advanced Demand Response (DR) scheme known as Demand Dispatch (DD) enable utilities to reshape demand curve to closely follow generation. An automated DD strategy is proposed as a solution to the issues related to high penetration of wind turbine generators (WTG) on micro grid. It basically balances the WTG power injection with real time controlled dispatchable loads. DD adopts smart communication for real time data collection as well as for dispatchable load management. A field implementation of DD in maintaining voltage stability in a DC microgrid with micro-WTG (m-WTG) is studied. The experiment results presented validate the scheme.

V. P. Sidharthan, A., S. Lingam, and K. Vijith, “Brushless DC motor driven plug in electric vehicle”, International Journal of Applied Engineering Research, vol. 10, pp. 3420-3424, 2015.[Abstract]

Global warming and noise pollution are serious ailments plaguing today's world. This paper deals with the electric scooter in which a Brushless DC(BLDC) motor is incorporated at the rear wheel of the scooter. The controlling of BLDC motor is done by a Motor Control Unit(MCU) in which the motor rotates based on current commutation. With the hall sensor outputs at each position of rotor there will be a switching scheme of six different states. Start stop and speed control of vehicle are controlled by the MCU. A 60V,1000W BLDC Motor is selected to drive the vehicle. The mathematical modelling of BLDC motor is implemented in matlab simulink. Also the closed loop speed control of BLDC motor is done in matlab. Hardware control of motor is done using Arduino uno development board in which Atmega 328 microcontroller is embedded. Corresponding pulses are obtained to drive each switch at different commutation states. © Research India Publications.
