SiC MOSFET and IGBT Hybrid Shunt Active Filter and its Application on a 10 KVA Harmonic Load System
This paper introduces a energy efficient, cost effective hybrid shunt active filter SAF concept and it application on a 10 kVA harmonic load system, with current harmonic rejection capability compared to IGBT based SAF solutions. Normally, IGBT based Shunt Active Filter designs face difficulty in higher order harmonics mitigations due to restricted switching frequency of […]
Microcontroller Control Thermoelectric heating and Cooling System using TEC1 12706
Nowadays microcontroller based automatic temperature heating and cooling control system is designed and constructed for the drinking water. The main function of heating and cooling are done by thermoelectric module TEC1 12706. The PIC 16 series, PIC16F887 is used as the main controller of the control system which decides the water temperature based on ds1820. […]
Regenerative Braking and Controlling of Hybrid Energy Storage System for an e Vehicle
Electrical vehicle with its high efficiency, noiseless operation and effective elimination of toxic exhaust gases have gained attention this decade. In earlier times, when conventional vehicles were used a large amount of energy was wasted due to the friction between the wheels and brake pads. In regenerative braking instead of wasting the energy produced during […]
Solar Powered Water Pump with Improved Efficiency
In this paper it deals with speed sensor less induction motor drive with improved efficiency. A solar PV array is used for water pumping using IMD. In order to increase the efficiency and reduce the cost many sensors are eliminated. Also an additional boost converter that is used to increase the voltage from PV. Rotor […]
