Life Interactive UPS Systems
The block diagram of lien integrative UPS is shown in figure when the main supply is ON static switch remains closed and load is connected to mains through an inductance L. In this condition the battery bank the DC through inverter which is used in as charger now.
Under the condition of power failure the main static switch becomes open. In this condition the battery bank supplies the power to the load through the inverter.
Q. Counter-controlled analog to digital converter? Figure shows the block diagram of a counter-controlledA/Dconverter. Resetting the binary counter to zero produces D/A output
Determine i L (t) and v C (t) for t> 0 in the circuit given in Figure.
Q. What do you mean by Output Voltage Swing? Ideally this is equal to the difference between the two supply rail voltages, although in practice it is a few volts less.
Machine Language ( First Generation Language) As we have already discussed that all digital circuits can identify only two states which can be specified by 0 and i henc
Q. Regions of operation in BJT ? Transistor find many applications like amplifier, switch etc. depending upon the polarity and the magnitude of the applied voltages across the
Q. A paraboloidal antenna has an aperture ef?ciency of 0.6 and a diameter D = 100λ at 6 GHz. Illumination by the feed is such that the beamwidths of the principal-plane secondary p
Network analysis software: GIS with a socket for network analysis software (Sec. 11.4) and availability of load related data from AMR based meter data acquisition system will
The far-field pattern of an antenna can be modeled as the two dimensional Fourier Transform of the aperture. 1. Determine the 2D Fourier Transform for the function
Q. Describe Pulse dialling? Pulse dialling: 1. Generated through make and break contact. 2. DC Current pulse is generated. 3. Each number is separated by a short
