Switching Characteristics
Switching characteristics are also know as dynamic or transient characteristics these characteristics give the information about the time variation with different voltage across teh thyrisotr and time variation with different currents through thyristor when thyristor comes from forwards off state to on state ( turn on period) and from on state to forward blocking state ( turn off period) the switching characteristics of SCR are shown in figure.
Dry type 10KVA-3ph-440/230v Dyn11. If we decide to wound above such specification, what current to be taken i.e. phase current or line current 7.57A or 13.12A
Vital parameters of regulator quality: 1. The output voltage's temperature coefficient of is the change in output voltage with temperature (perhaps averaged over a certain tem
If E b /N 0 = 20 in a coherent ASK system, find the value of Eb/N0 that is needed in a noncoherent ASK system to yield the same value of Pe as the coherent system.
Q. In the Wheatstone bridge circuit shown in Figure, R 1 = 16, R 2 = 8, and R 3 = 40; R 4 is the unknown resistance. RM is the galvanometer resistance of 6 . If no current
Q. A three-phase ac motor, used to drive a draft fan, is connected to a 60-Hz voltage supply. At noload, the speed is 1188 r/min; at full load, the speed drops to 1128 r/min. (a
how to calculate the the stability factor
i need a line diagram sample of a large network, i need to practice how to draw and design such network
what is digital signal
Design a low noise amplifier using an Infineon RF transistor BFP640. The amplifier is to be used to amplify the L2 GPS signal and so the centre frequency is 1227MHz and bandwidth 4
Q. A commercial FMstation broadcasts a signal with 180-kHz bandwidth when |f(t)|max = 2 V. Find kFM for the modulator if the spectral extent of f (t) is 30 kHz, by using Carson's r
