The ripple on the control voltage creates sidebands around the carrier at the output of a PLL, equivalently disturbing the phase of the VCO.
Explain why the PLL suppresses the VCO phase noise (within the loop bandwidth) but not the sidebands due to the ripple.
What are the three possible ways of constructing three-phase two winding transformers and give brief description of the constructional features of each type.
Explanation to "Electric circuits" question, The voltage across a load is v(t) = 260 sin (377t + 10 °) and the current through the load is i = 100 sin (377t + 10°). What is the RMS power?
The magnetic saturation of the machine can be ignored. The harmonics in the current and voltage to the machine can be ignored. Calculate the active power (watts) to the machine from the VVVF inverter.
A 345-kV, three-phase transmission line delivers 500 MVA,0.866 power factos lagging, to a three-phase load connected to itsreceiving end termines. Assume that the load is Δ connectedand the voltage at the receiving end is 345kV.
Obtain the required diameter of the rotor blades of the wind turbine and calculate the required capacitor bank that allows a stand-alone operation of the induction generator.
