rectification, waveforms, voltage ripples Flashcards
Hz (hertz) = 1/s or ____________. US homes run on _____
one cycle per second, 60 Hz
The velocity of a wave is equal to the product of _____________ and ________________
its wavelength and frequency (number of cycles per second)
velocity of a wave is (independent of/dependent on) its intensity
independent of
One half the range between the wave peak and valley over which the sine waves varies or the equilibrium position
wave amplitude
When current flows towards the anode, the diode becomes a __________ and allows the current to flow through the _________________
conductor, P and N type crystals
When current flows towards the cathode end, the diode blocks the flow as the free electrons of the N-Type Crystals and electron holes (or traps) of the P-Type Crystals pull away from each making the diode a __________
resistor
because of its ability to act as both a conductor and resistor, the diode is known as a ___________
semi-conductor
waveform with varying power and a large gap is found with _____________
half-wave rectification
A full wave rectifier is defined as a rectifier that converts ______________________________________-
the complete cycle of alternating current into pulsating DC
Unlike half-wave rectifiers that utilize only _______________________, full wave rectifiers utilize the full cycle
the halfwave of the input AC cycle
fluctuation from zero the maximum voltage (wave peak)
ripple
what is the solution for ripple?
use three AC waveforms at the same time
three-phase 6 pulse is ___% ripple
13
three-phase 12 pulse is ___% ripple
3.5
________ of the kVp selected for three-phase 6 pulse to __________ for three-phase 12 pulse.
87-100%, 96.5-100%
