In order to improve the efficiency of DC–DC converter common active clamp boost circuit is used. This can be achieved by interleaving the coupled-inductor boost converters. The Clamp boost converter is used to clamp the voltage stresses of all the switches in the interleaved converters, caused by the leakage inductances present in the practical coupled inductors, to a low voltage level by use of PID controller. The leakage energies of the interleaved converters are collected in a clamp capacitor and recycled to the output by the clamp boost converter controlled by the PID controller. The proposed converter achieves high efficiency because of the recycling of the leakage energies, reduction of the switch voltage stress, and reduction of the output diode’s reverse recovery problem. Detailed analysis and design of the proposed converter are carried out. The effectiveness of the control strategies have been verified by simulation results.

The main criteria required for all the electrical and electronic device is the voltage. It plays vital role in a power quality. It is planned to provide a transformer with multiple taps and selecting the taps required for the moment will be automatically selected by the on-load changeover system which is operated by the controller. Computer acts as a controller with the aid of the C software. Voltage transducers are used to sense the voltage and ADC to convert into digital signals. These digital signals arte interfaced with computer which in turns operates the On Load Tap Changers (OLTC). Suitable taps are selected and its drive relays are operated by the computer through opto-coupler and switching transistors.Keywords
