Input power factor in a controlled rectifier refers to the ratio of real power (active power) to apparent power in the input circuit of the rectifier. It indicates how effectively the rectifier converts the input AC power into usable DC power, with a higher power factor signifying better efficiency and reduced reactive power. A controlled rectifier typically employs thyristors or other semiconductor devices to manage the phase angle of the input current, which can improve the power factor compared to uncontrolled rectifiers. A poor power factor can lead to increased losses and reduced system performance.

What is meant by Single phase half controlled bridge rectifier?
This is actually called a single phase half converter and it is used to have an adjustable DC output voltage. It is like a bridge rectifier but two of the diodes are replaced with a solid state switch, SCR for example, and there is also a freewheeling diode in parallel with the load. A half converted can have an output voltage that is adjustable from 0.9*E to 0 volts. It does this be adjusting the firing angle of the switches. There is also a full converted and the difference is that it has an output voltage from + 0.9*E to - 0.9*E volts.
What is meant by hysteresis error of a transducer?
Hysteresis error in a transducer refers to the discrepancy in output readings when the input is varied in different directions. Specifically, it occurs when a transducer's output does not return to the same value when the input is approached from different paths, indicating a lag or dependence on previous states. This can lead to inaccuracies in measurement and is an important factor to consider in the calibration and performance evaluation of transducers.
What is meant by input stream?
An input stream is a character sequence device or buffer from which input can be gathered. The standard input stream is usually a keyboard, data file or the output stream from another program. The user of the program can normally decide where standard input may be redirected from when launching the program, typically defaulting to the keyboard.
Define what is meant by a common-mode input signal?
Common mode input signal is a term associated with Differential amplifiers.There would be two input signals in a diff. amplifier.The common component of these two signals is called common mode input signal.ie.if V1 and V2 are the two input signals then (v1+V2)/2 is the common mode input signal.Also |v1-v2| is the difference mode input signal.
What is meant by z source inverter?
the z-source inverter use an input diode and x-shape network of capacitors and inductor
What is meant by 'verification of data'?
It is the checking of data input to a system to ensure that it is what is meant to have been input.
What is meant by 'OA' in OA79 and '1N' in 1N4001?
IN IN = 1N: Refers to the number of junctions (1N= 1 junction). O= Germanium, A= rectifier diode, so OA = germanium rectifier diode.
Why diode can't use as amplifier?
A2. For amplification to take place, one needs three terminals; an input, an output, and a control signal.This indicates the original " valve" naming; after a mechanical valve, where a small effort on a (hydraulic) valve may be used to control a larger effort of the controlled fluid.A1. If u meant why diode can't be used as an amplifier diode is used as a rectifier..it converts ac current to dc and there is an inbuilt voltage drop... so it can't be used as an amplifier
Was the significance of the Allies?
It meant that Hitler no longer controlled Europe and Japan no longer controlled the Pacific.
What is meant by output nerve cell and input nerve cell?
Input nerve cells is something u can see.
What is meant by bidirectional power flow?
I guess it means that in your system, you can make the input output and vice versa. Example, if you have power conditioning unit (PCU) that either operates as rectifier or inverter. That means your PCU has bidirectional power flow. you can then operate it on the mode you need; rectification or inversiion mode. I hope that was helpfull Naeem, Mohammad
What is meant by half cycles in rectifiers and diodes?
when the input voltage is an ac signal in a rectifier or diode circuit the input works in two cycles.It's a wave form.starting from zero it reaches to its peak value and gradually reduced to zero.this is the 1st half cycle.now the signal reduces below zero and reached to tye negative peak value and again rises to zero.this is the 2nd half cycle.Together this two half cycles complete a full cycle.
What is meant by the term drainage basin?
An access point for controlled leakage.

What is meant by hard copy input?
the device that put an enformation to computer and that cannot be erase
What is meant by double tuned amplifier?
An amplifier with tuned filters on both input and output.
What is meant by the terms 'active high input' and 'active low input'?
The term "active low" means that the input on an IC requires a logic low for it to be activated, i.e a low voltage (of course the voltage range is dependent on the technology, TTL, CMOS etc) Active high is the opposite... the input requires a logic high for it to be activated. A simple example to illustrate, an 8bit counter can count UP/DOWN this functionality is controlled with only one pin, an active high on that pin to count up or low to count down.
