What Is Delime Cycle Insinger

Vertical scanning circuit is responsible for making the electron beam moves vertically, ie from top to bottom the screen.
So who should be to circulate a current through the windings which form the vertical section of the yoke so that its magnetic field influence on the electron beam onto the screen, or electron beams in the case of a color display .
is of vital importance as this circuit is who we draw the 525 horizontal lines in association with the Horizontal circuit, these lines should have the same spacing between lines (Vertical Linearity) to reproduce the image without distortion, so the current flowing through the Vertical Yoke must have a special feature.
This signal is generated or created a circuit called Vertical Oscillator, but before we know how to create first focus on the part that handles the power, which is one that most fails.
The vertical output stage used in TV but not so new is that which contains two power transistors usually working in Case 375 Push-Pull assembly which means that when one drives the other off and that is achieved two simultaneous signals generated in the vertical oscillations.

In this circuit we have two transistors Q501 and Q502 identified as. Q501 is in charge of "Load", the C520 from the current through the Vertical Yoke, when the C520 starts its charge creates a magnetic field that makes the Yugo s is located at the top of the screen.
As the C520 is loaded, its current decreases as well as its magnetic field and that is where the beam goes down over time looking for the center or point of rest. Past
certain time and when the beam is at the center of the screen horizontally, the signal generated by the oscillator and vertical Driver makes the Q501 was initially driving or active, quit and turn on Q502.
In conducting the Q502 (remember that the electronic structure is such that when the drives Q501 Q502 is cut and vice versa) Q501 stops charging the C520, but when driving the C520 Q502 begins to discharge. This implies that the current in the Yugo changes direction, so the magnetic field also changes and that makes the beam is going from center to the bottom of the screen. This will complete the "fill" the screen.

As you know one you see the beam reached the bottom of the screen, this should rise to the top left of the screen.
It does so by suspending in a "sudden" or unintended current that is flowing through the yoke.
This is achieved when Q502 suspended the "download" total of C520. We know that when you stop electricity flow in a winding natural reaction is that this auto generated a voltage spike, the peak generated in the Yugo is responsible for raising the beam at the top of the screen and the same instant the Q501 has already begun to "load" again the C520, beginning a new cycle of work, repeated 59.94 Hz
These signals we have in the following figure helps us understand what we have explained. Notice how the waveform is such that half cycle influences the Q502 ("ON" or driving) while the Q501 is "off" or off. The other remaining half cycle is responsible for reversing the operation of transistors.
