To get the V03‚ three devices- a resistor‚ a capacitor and voltage multiplier are used. The output voltage across the resistor (Ry) and capacitor (C) are multiplied using a analog multiplier AD633. According to the port characteristics of AD844‚ Vx=Vy; iy=0; iz=ix; Vw=Vz In figure 4‚ stage 1 is a current to voltage converter‚ by analyzing the circuit

SMART ENERGY METER A smart meter is usually an electrical meter that records consumption of electric energy in intervals of an hour or less and communicates that information at least daily back to the utility for monitoring and billing purposes. Smart meters enable two-way communication between the meter and the central system. Unlike home energy monitors‚ smart meters can gather data for remote reporting. Smart Meters" usually involve real-time or near real-time sensors‚ power outage notification

voltage supplied by the transformer’s secondary winding. For most applications the output ripple produced by these circuits is too high. However‚ for some applications - driving small motors or lamps‚ for example - they are satisfactory. If a filter capacitor is added after the rectifier diodes the output voltage waveform is improved considerably. Figures 3 and 4 show two classic circuits commonly used to obtain continuous voltages starting from an alternating voltage. The Figure 3 circuit uses a center-tapped
