What is the maximum DC voltage you could expect to obtain from a transformer with an 18V rms secondary using a full rectifier circuit with a filter capacitor?
25.46V assuming output of transformer is pure sinewave.

Block diagram of smps?
A block diagram of SMPS has a main filter, primary rectifier, and power switch. It also has an output transformer, secondary rectifier, smoothing circuit, and controller.
Why excitation transformer vector group is only DY5?
This is basically to reduce the harmonics injected back in the grid which are generated because of the controller rectifier circuit (Thyristor Bridge - B6C) after the transformer secondary.

A circuit diagram consisting of diode and transformer?
This is probably a half-wave rectifier.Rectifiers are used to convert AC to "DC". A half-wave rectifier can be constructed with a transformer and a diode connected between the positive terminal of transformer secondary and the load. This doesn't provide DC power to the load, but instead blocks the negative portions of the AC signal and only allows current to flow into the load while the AC voltage is positive. A capacitor is typically connected across the load to smooth out the voltage, making the input to the load more DC-like. The capacitor charges up when the AC voltage is positive and the diode is conducting, then discharges through the load when the diode is not conducting. This is still not DC power since there is a certain amount of ripple, or variation in the load voltage. Selection of the capacitor value is important to reduce ripple to an acceptable level. The transformer is simply used to change the AC voltage to whatever is desired.The half-wave rectifier is a very simple circuit. Other kinds rectifiers, for instance a full-wave rectifier, offer better performance.
Why does a phase in secondary side in distribution transformer give low voltage?
transformer is busted; if input voltage is normal you have short circuit or open circuit somewhere

What converts an alternating current to diredt current?
Alternating Current can be converted to Direct Current by using a DC Converter which contain a Bridge Circuit , a Capacitor and if needed a Transformer.CommentA 'DC converter' is normally called a rectifier.
Why excitation transformer vector group is only DY5?
This is basically to reduce the harmonics injected back in the grid which are generated because of the controller rectifier circuit (Thyristor Bridge - B6C) after the transformer secondary.
Why capacitor used in rectifier circuit?
To smooth the output of the pulsating DC.
What is the maximum DC voltage you could expect to obtain from a transformer with an 18V rms secondary using a bridge rectifier circuit with a filter capacitor?
The maximum DC voltage you could expect to obtain from a transformer with an 18V rms secondary using a bridge rectifier circuit with a filter capacitor is about 24V.This assumes a truly sinusoidal AC waveform, and a forward conductioin voltage of 0.7 volts across each diode.Multiply 18 by the square root of two, and subtract two times the diode voltage.The maximum is the peak value. If there is any load on the output, there will be some ripple, but the peak value will still be around 24V.To calculate the output voltage of single phase diode bridge it is reasonable to assume a filter capacitor exists across the output and realize that it will be charged to the maximum voltage available to it.
Why you are using the bridge rectifier in most of the circuits instead of full wave rectifier eventhough the output of both are same?
If diode in the bridge circuit becomes open the circuit will become a half wave rectifier instead, but if a diode in a full wave rectifier opens then the whole circuit becomes open. (No current flow). ************************************************************** The outputs of the bridge and the two-diode full wave rectifier are not the same. For the rectified voltage to be the same value, the two-diode full wave rectifier must be supplied from a centre tapped transformer winding, the total voltage of which is twice that necessary for the bridge rectifier circuit. Furthermore, the maximum d.c. which may be drawn from the centre tapped transformer/two-diode arrangement, assuming capacitive filtering, is the same value as the transformer secondary winding's capacity. In the case of the bridge, the maximum d.c. which may be drawn, also assuming capacitive filtering, is 62% of the transformer secondary winding's capacity.
What is the advantage of full wave capacitor rectifier circuit?
to get maximum dc output
How do you determine the size of acapacitor in a rectifier circuit?
ANSWER In rectifiers for power supplies, the capacitor size is determined by the allowable ripple on the output. This can be determined by the rate at which the capacitor is drained. Specifically, this rate is the current drawn from the capacitor. Assume a half wave rectifier made from four diodes. For part of the cycle, the output current is supplied by the rectifier diode. This is also when the capacitor is charged. While the rectifier is not supplying current -- when the input waveform has dropped below the output voltage -- the capacitor must supply the current. Then, as the input waveform rises above the capacitor voltage, the rectifier supplies the current to charge the capacitor and the output circuit.
