AC Link Chopper
This copper has two stage conversion. First DC is converted into AC by the use of inverter. The magnitude of AC voltage is varied by the transformer and it is converted back to dc using a rectifier.

What we have seen for practical power supplies applies to any electrical circuit provided it contains only linear components
Use the offset diode model with a threshold voltage of 0.6 V to determine the value of v 1 for which the diode D will first conduct in the circuit of Figure(a).
Explain Resistivity. Resistivity : Resistance R of a wire containing cross-sectional area A and length L maintain the relationship, - R α L and R α 1/A; that is resulting R α
Voltage is referred as Potential difference among two points. Potential means its force. I think so.voltage defination is 100% correct.
AC Machines: We have learnt the fundamental concepts of the transformer, induction motors and special type fractional kilowatt (kW) machines. In the section of transformer you
Write explanatory notes on Paging. The memory paging mechanism located inside the 80386 and above permits any physical memory location to be allocated to any linear address. Th
Q. Resultant air-gap flux of induction machine? The resultant air-gap flux is produced by the combined mmfs of the stator and rotor currents. For the sake of conceptual and ana
1) Use plot of the stock return and consider the Autocorrelation Function to determine the auto-regressive structure of the data and explain why you think the return is stationary
A synchronous motor has the following parameters per phase. E=2kv, Eo=5kv, X2=3ohms, and I=700amps. Draw the phasor diagram and determine (a) power angle delta, (b) active po
