چکیده :

In this paper, we in order to study the proximity and skin effects and in result obtaining circuit model of coil turns of MCG generator use from a new method that call non uniform elementary cells (NUEC) model. This paper presents a new approach for calculate the current of conductor coil turns of the magneto flux cumulative generator (MCG) accurately. This approach is based on the electrical structure method and electrical equations and laws in high frequency. By using this new method, we can consider the proximity effects (PE) and skin effects (SE) in turns of MCG generator coil in high frequency and finally, affect them on operation of the MCG generator. Inductance and resistance are dependent on frequency and this is because of proximity and skin effects (PE, SE effects). In this paper, with considering the frequency, we have regarded the proximity and skin effects in a model of MCG and surveyed its effect an efficiency of MCG. For considering proximity and skin effects, non uniform elementary cells (NUEC) model for obtaining circuit model of coil turns has been used. We in discussion continue, will insert central cylindrical liner effects and instantaneous flux losses effects in calculations and will study affects them on generator operation. In the end we will obtain parameters of current gain (C.G) , figure of merit (F.M) , energy gain (E.G ) of MCG generator in four states with and without liner and with and without instantaneous flux losses effects and finally will discusses and analyze theirs effects on operation of MCG generator. We will show that existence of liner cause of decrease in all three parameters C.G, F.M and E.G of generator and so cause of reduction of MCG generator efficiency will be. Also we will see that instantaneous flux losses cause of efficiency reduction of generator will be. In the end it is shown that the inductance and resistance and finally the current of the coil turns of the MCG generator how will change in time of explosive explosion in central cylindrical liner of generator. It is show that by explosion progress in inner of central cylindrical liner and move explosion to front and expand liner and in result of reduction of coil turns number of generator, decreases the equivalent inductance and resistance of MCG generator and finally increase current of generators coil turns. The presented method in this paper is very useful for correct design of MCG generators.
