Given these three points‚ which are provided by all commercial array datasheets‚ the method finds the best I–V equation for the single-diode photovoltaic (PV) model including the effect of the series and parallel resistances‚ and warranties that the maximum power of the model matches with the maximum power of the real array. With the parameters of the adjusted I–V equation‚ one can

ABSTRACT Capacitance measurement is of immense importance in the field of electronics. An instrument that measures capacitance to accuracy better than 0.5% has been improvised and rendered auto-ranging by means of an 89c51 circuit. The principle is that of a “direct” or fundamental principle of the time constant of the component. For e.g.‚ the time taken to charge a capacitor to 50% of the applied voltage is given by 0.5 V = V (1- exp (-t/τ) ) The value of t is determined as 0.69314718τ. Knowing

CHAPTER I ------------------------------------------------- INTRODUCTION 1.1 Introduction Portable electronic devices are very popular nowadays. As the usage of these portable electronic devices is increasing‚ the demands for longer battery life are also increasing. These batteries need to be recharged or replaced periodically. It is a hassle to charge or change the battery after a while‚ especially when there is no power outlet around. Therefore‚ our team is inspired to design a wireless

Amplitude modulation is when the modulating audio is combined with a radio frequency carrier is such a way that the total wave power is made to vary in accordance with the modulating audio. The normal type of AM is double sideband or‚ to be more specific‚ double sideband full carrier. Recall that the carrier does not convey any intelligence
