A Brief Review on Induction heating
Abstract: Induction heating is the method of heating an electrically conducting material (usually a metal) by electromagnetic induction, through eddy currents generating heat in the object. An induction heater is an electromagnet and an electronic oscillator that passes through the electromagnet through a high-frequency alternating current (AC). The rapidly alternating magnetic field penetrates the artifact, producing the conductor's electrical currents called eddy currents. The eddy currents flow through Joule heating through …

An Improvement of Out-of-Band Suppression in Common-Gate LNA with Transformer-Based Input Matching Network for BLE Applications
Abstract: The purpose of this paper is to improve out-of-band suppression in capacitive cross-coupling common-mode LNA with transformer-based input matching for BLE applications. Starting from an overview of the transformer-based matching network, the problematic issue is addressed through analytical considerations and its solution is presented. Transformer-based matching introduces an undesired peak response by an extra conjugate pole pair owing to the imperfect magnetic coupling of the transformer which degrades the suppression …

Transient Analysis of self excited Induction generator with ELC
Abstract: — Fast depletion of fossil fuels has drawn attention towards the use of nonconventional energy sources like wind, biomass, tidal/wave, and small hydro potential. In remote locations, harnessing of electrical energy from such local resources can be cheaper and easier compared to grid connection, which involves long transmission lines and associated losses. A micro-hydro system using natural hydro potential with minimal civil works is a strong candidate in this race. …
