Why smps convert ac to dc and again to dc to dc?
first it converts ac to dc as rectifier But the required dc voltage is obtained by taking average of on & off DC input voltage.
What do you mean by offset adjustment in electronics?
Voltage or current Offset is the voltage or current seen at the outputeven when no input is applied. This happens due to various reasons such as imbalance in the device, asymmetry and many more. So, offset adjustment means, providing the required input externally, so that the output voltage and current are zero.
What is a voltage rectifier?
A rectifier is a device that is used to "change" (rectify) some kind of alternating current (AC) into direct current (DC). There is more to the story, but basically the rectifier is a "one-way" device that will permit current to flow though it in only one direction. That way one or more of these devices can be used in different curcuit configurations to change an AC input into a DC output.
How do you derive PIV of Bridge rectifier?
A: The input peak value is the guide for PIV
Why capacitor in transistor amplifier circuit at input?
Because capacitor not allow to pass dc voltage,but capacitor allow ac voltage and signal.Purpose is to block dc voltage.That is coupling condenser.
Which type of rectifier has the greatest output voltage for the same input voltage and trasformer turns ratio?
Bridge Rectifier
What is voltage regulation of a rectifier?
A: actually a full wave rectifier does not regulate. It will however follow the input minus diodes voltage drops. depending on current it is assumed to be .6 to .7 volts for silicon diodes.
How do rectifier circuits stabilize the output voltage when the input voltage is subject to fluctuations?
Rectifiers don't "stabilize the output voltage" of rectifier circuits when input voltage fluctuates. The rectifiers just rectify the input, and the output will fluctuate as the input does. Another form of "conditioning" of the rectified output is needed to address the issue of fluctuations. And we use the term regulation to talk about the effect of "stabilizing" an output voltage. Through regulation, the output will be resistant to changes in voltage when changes in the input voltage occur.
What is the schematic of a selenium rectifier?
A selenium rectifier typically consists of a stack of alternating selenium disks with metal electrodes connecting them. The input AC voltage is applied across the stack, and the rectified output is taken from the ends of the stack. A resistor is often included in series with the rectifier to limit current flow.
What causes the ripple voltage on the output of a capacitor-input filter?
Ripple voltage in a capacitor-input filter primarily arises from the charging and discharging cycles of the capacitor. When the rectifier conducts, the capacitor charges to the peak voltage of the input signal. As the load draws current, the capacitor discharges, causing the voltage to drop until the rectifier conducts again, resulting in a voltage ripple. The magnitude of this ripple depends on factors such as the load current, capacitance value, and input frequency.
What is the nature of the output voltage of half wave and full wave rectifiers with that of the input voltage?
In a half wave rectifier voltage across load resistance is not consistent, because for positive pulse of input voltage diode work as a forward bias i,e half wave rectifier treat as closed circuit and for negative pulse of a input voltage diode work as a reverse bias so no current flow through circuit. therefore voltage output is not consistent. In full wave rectifier two diodes are used at the both side of secondary coil of transformer. due to that for positive pulse of input voltage one diode diode work as a forward bias another as a reverse bias. for negative pulse of a input voltage second diode work as a forward bias another as a reverse bias,so consistent voltage can be provided by full wave rectifier.the nature of output voltage of half wave rectifier and full wave rectifier is that it flows through with only one polarity either in positive or negative in the circuit.
What peak reverse voltage is needed on a bridge rectifier at 120 ac input?
120 * square root of 2
. Which type of full-wave rectifier has the greater output voltage for the same input voltage and transformers turn ratio?
well when you see on basis of output voltage the centre tapped transformers is .
What is the peak value of the input to a half wave rectifier if the half wave rectifier is 10V?
In this case, the peak voltage, which is half the peak to peak voltage, is 100 volts. Additionally, the half-wave rectifier will only provide an output for half the input cycle. In the case of a full wave rectifier, the RMS output voltage would be about 0.707 times the value of the peak voltage (100 volts), which would be about 70.7 volts. But with the output operating only half the time (because of the half wave rectification), the average output voltage will be half the 70.7 volts, or about 35.35 volts RMS.
What is the input and output of a load cell?
The input of a load cell is the force or weight applied to it. The output of a load cell is an electrical signal, typically in the form of voltage or current, that is proportional to the applied force or weight.
Why does the output frequency of a full wave rectifier double that of input frequency?
One cycle of the AC input consists of a positive half-cycle followed be a negative half cycle. The FW rectifier basically reverses the polarity of one of the half-cycles, so there are now two positive pulses per single input cycle, effectively doubling the frequency. Of course the rectifier may be wired for the opposite polarity, with two negative pulses per input cycle, but the same principle applies.
Can you say which bridge rectifier voltage has the highest out put voltage?
A: NO the power output will be higher. Bridge rectifiers do not provide more voltage output it just add more power by rectifying both positive and negative voltage of the AC input
