Resisting the tide of post-modernity may be difficult, but I will attempt it anyway.

Close magnetic coupling between the primary winding 14 and supplemental winding 41 as a result of the layer winding arrangement produces accurate regulation of the supplemental winding voltage. Many contemporary “televisions” more correctly named as displays would not have this level of staying power, many would ware out or require major services within just five years or less and of course, there is that perennial bug bear of planned obsolescence where components are deliberately designed to fail and, or manufactured with limited edition specificities Decreases in the ac line voltage or increased circuit loading will cause an increase in the SCR conduction time and an increase in line voltage will result in a decrease in SCR conduction time.

Every CRT Television saved let revive knowledge, thoughts, moments of the past life which will never return again When the collector voltage exceeds the combination of the voltage level on capacitor 21 and the conduction threshold voltage of diode 20, diode 20 is rendered conductive, permitting winding 14 energy to charge capacitor When transistor 16 is turned off, by action of the switching pulses from regulator control circuit 22, the stored inductive energy in winding 14 causes the collector-emitter voltage of transistor 16 to rise.

The potential difference between primary winding 14 and supplemental winding 41 is relatively small, as contrasted to the potential difference between primary winding 14 and high voltage winding 23, for example.

The voltage represented by the spike in FIG. When transistor 16 turns off, its collector voltage rapidly rises, creating an inductive voltage spike as shown in FIG. Transistor 16 is switched on at a time t 2 and off at time t 4resulting in a decreased current flow in primary winding 14 and supplemental winding Limiting the switch duty cycle also limits the amount of energy that may be transferred to the load windings which may limit the ability of the power supply to accurately regulate the load circuit voltages under extreme line voltage and circuit loading conditions.

The L is a horizontal, slide – out chassis which, in addition to the larger screen sizes, is also used in 14 and 15in. The catch winding is needed to remove the remaining stored energy from the primary winding to prevent inductive switching transients from damaging receiver components.

Current flow in supplemental winding 41 I 41 decreases as the darasheet energy in the winding decreases. The K is an upright, hinge -back type that’s akin to the H and J chassis.

The primary winding comprises one half of a bifilar-wound coil pair with the other half of the coil pair operable as a catch winding to return stored energy in the coil back at the unregulated supply when the transistor switch is turned off. An arrangement for electrically isolating the receiver load circuits from the ac line via the high voltage power transformer datsaheet disclosed in a copending application entitled “Regulated Power Supply Circuit”, Ser.

Today, the West is headed for the abyss. Doing so it starts from the most recent post to the older post simple clicking on the Older Post button on the bottom of each page after readingpost after post. Following this idea around a bit, convinced me that a collection of the peculiar alone could not hope to survive on its own merits, but a museum that gave equal display space to the popular and the unpopular, would bring things to the attention of the average person that he has previously passed by or been shielded from.

It’s useful since the content of the site is very large. Transistor 16 is switched by signals from a regulator control circuit 22 via an isolation transformer 28 to control the conduction of current from the unregulated voltage source through winding 14 in a manner that will be explained later.

Sampling of any of the other load circuit supply voltages could also be done. When transistor 16 turns off, at time t 3this coupling causes the voltage across winding 41 V 41 to increase, as shown in FIG. Note that if you don’t find what you searched for, try it after a period of time; the site is a never ending job!

To prevent a degradation of the voltage regulating capabilities of the receiver under these conditions, a supplemental winding 41 of transformer 14 is provided and operates in the following manner. This permits windings 14 and 41 to be layer-wound as previously described in order to provide tight magnetic coupling yet allows windings 14 and 41 to be electrically isolated through the use, for example, of 20 mils of Mylar between windings 14 and Many of the circuits in television receivers require carefully regulated power supplies in order to operate properly.

It’s a matter of culture. This insures that all of the stored energy in the primary winding can be transferred to the catch winding. Comments on this blog may be blocked or deleted at any time. This is shown in FIG.

Such an arrangement is required when it is desired to provide the receiver with the capability to accept a direct video signal input, for example, from a video tape recorder or a video disc player, or from a home computer. Transformer 15 also includes a number of secondary windings and a tertiary winding 23, which generates a high voltage of the order of 25 KV at an ultor terminal 24 to be applied to the anode of a kinescope not shown.

Don’t forget the pastthe end of the world is upon us! This unregulated voltage is applied to one terminal of a primary winding 14 of a high voltage power transformer These insulation and physical separation requirements may produce a transformer having a reduced primary to load winding magnetic coupling compared to a transformer that does not provide as great a degree of electrical isolation. The amount of energy dagasheet may be transferred in this way is dependent on factors which include the conduction time of transistor 16 and the degree of magnetic coupling between the primary winding 14 and the load windings.

The voltage an590 via the secondary and tertiary associated load circuits are carefully regulated in the following manner, which will be explained with reference to FIG. Another secondary winding 27 is a5n900 to a horizontal deflection circuit 30, which comprises a horizontal output transistor 31, a retrace capacitor 32, a damper vatasheet 33, a deflection yoke winding 34, and a deflection waveform S-shaping capacitor Additional receiver circuits may be subject to excessive electrical stresses or may be damaged if supply voltages are not held within acceptable limits.

Current flow in winding 41 may also be terminated by the switching of transistor 16 terminating conduction of winding
