What do you mean by pulsating voltage?
In digital systems, pulses comprise brief bursts of DC (direct current) voltage, with each burst having an abrupt beginning (or rise) and an abrupt ending (or decay). In digital circuits, pulses can make the voltage either more positive or more negative.
How do you pulsate in DC?
To obtain pulsating DC, use rectifier after oscillator, i.e. output of oscillator is connected to rectifier. For frequency upto 1 KHz, normal rectifier diode will work. For higher frequency use point contact diode or diodes used for high frequency rectification.
What do you mean by pulsating current?
: a direct current that has recurring more or less regular variations in magnitude.
Is there any difference between pulsating DC and a pure DC?
In a pure DC the voltage at any given moment is the same. In a pulsating DC, the average of the voltage is same. It’s basically an AC voltage superimposed with the DC.
How is pulsating DC current measured?
How To Measure Extreme Pulsed Currents (Pulsed Shunts Part 1)
Does pulsating DC have frequency?
No, DC current as defined as DC has no frequency.
What causes a DC motor to pulsate?
The current drops as rapid as the speed rises as current is a force that controls acceleration then rated load at rated RPM. Surge currents are always much higher than the static current rating. This means the supply cuts out from overcurrent causing shutdown then recovery, so you get a jerky pulsed acceleration.
Can transformer works on pulsating DC?
All Answers (8) Yes, the input to a transformer can and often is pulsating DC.
How do you smooth a pulsating DC current?
How to Smooth Out Pulsating DC – YouTube
Can a transformer work on pulsating DC?
What is the frequency of pulsating DC?
Therefore output dc pulsating voltage contains 60pps (pulse per sec). Frequency remains same for input and output so answer is 60pps.
Can we use pulsating DC to induction motor?
It is possible to cause an induction motor to move by applying short pulses of DC current. However the motion will not be predictable and the applied power will not be at all efficiently used unless the application of pulses conforms to a carefully calculated pattern.
