This paper is to study about the dc sweep analysis and also time domain transient analysis of the Electromagnetic interference of the pulse width modulation which is used for the domestic appliances. The current can be analyzed at the various level stages of the switching devices such as diode. The source has been detected and has to be mitigated the EMI noise. An exhaustive method for the selection of different power semiconductor switches for high frequency hybrid resonant inverter fed induction heater is presented here. Heating coil of the induction heater is made of litz wire which minimizes the skin effect and proximity effect at high operating frequency. With the calculated optimum values of inductance and resistance of heating coil at a particular operating frequency, high frequency hybrid resonant inverter topology has been simulated using PSPICE software as well as constructing the experimental mo del of same rating. Obtained the voltage waveforms across heating coil and current waveforms through it, have been taken for further analysis. Waveforms have been shown to justify the feasibility for real implementation of high frequency hybrid resonant inverter fed induction heater in domestic applications.Keywords

In this present day, use of renewable energy resources is very much increasing and in this one of energy source is solar energy. In this paper the integration of pv and multiple electric vehicle to micro grid is discussed. Applications of electric vehicles need to build a large number of charging stations. In order to reduce the grid load, it is necessary to develop smart electric vehicle charging stations. The Electric vehicle charging stations communicate with the gird. When grid load increase, electric vehicles battery discharge to the grid to improve grid stability. As distributed storage units, electric vehicles are important components of smart grid. The central component of electric vehicle is battery and the charge and discharge dynamics of battery model are dynamically validated experimentally with four batteries types. An interesting feature of this model is simplicity to extract the dynamic model parameters from batteries.Keywords

In olden days the use of wind power in mankind is the sail boat. Then demand of electricity is more. By using the conventional power plant unable to manage the demand of electricity. So the renewable energy can be used wind power mill. The modern grid requirement has caused the wind power system behave more like a conventional rotating generators. In these days windmill are used to power a house and also transfer power to the grid for purpose of maintaining voltage. In the existing system LCL filter is used to achieve half value of reactive power or harmonic current can be reduced. In the proposed system the adaptive filter can be used for better performance Furthermore, it is also found that the annual energy loss could even become lower with the optimized filter and thereby more energy production for the wind turbine.
