What is output of transformer AC or DC?

Transformers always output AC. You need rectification after that to get positive halfwaves followed by a capacitor(s) to smooth it out decently. If you power integrated circuits, you need a linear regulator also, to get smooth DC, say 7805.

What is the PIV necessary for the diode if transformer of 24/0 24 V is used?

The PIV of the diode used should be 2 times the Vp of the input sine wave. For 24V RMS, the Vp is 34 volts. PIV needed is 2 x 34 = 68 Volts.

What is DC power output?

The power at the input and output can be either alternating current (AC) or direct current (DC): Direct current (DC) occurs when the current flows in one constant direction. It usually comes from batteries, solar cells, or from AC/DC converters. DC is the preferred type of power for electronic devices.

What does a transformer Do AC to DC?

The transformer is used to step down or step up the AC voltage, with the principle of electromagnetic induction. After increasing or decreasing the AC voltage, the rectification circuit converts the AC voltage to DC voltage. An AC to DC transformer is a simple solution for powering up electronics from the AC mains.

What is the output of a transformer?

The output voltage of a transformer can be less than, greater than, or equal to the input voltage, depending on the ratio of the number of loops in their coils. Some transformers even provide a variable output by allowing connection to be made at different points on the secondary coil.

What is Diode PIV?

Peak Inverse Voltage (PIV) or Peak Reverse Voltage (PRV) refer to the maximum voltage a diode or other device can withstand in the reverse-biased direction before breakdown.

What is the expansion of PIV?

Particle Image Velocimetry (PIV) is a very common and useful tool to investigate the flow phenomena in models of blood vessels, heart valves or artificial organs. A 2D high-resolution PIV system has been developed, setup and successfully tested.
