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 datashfet 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. This means that there an59000 be a delay between the submission and the eventual appearance of your comment. This in turn energizes the electrically isolated load circuit windings in order an59000 power the associated load circuits.

Sampling of the volt supply is shown for example only. As the load circuit power requirements decrease or the ac line voltage increases, transistor 16 conducts for a shorter period of time each horizontal interval, as shown by the dashed lines in the waveforms of FIG.

The K is an upright, hinge -back type that’s akin to the H and J chassis.

One type of voltage regulating circuit utilizes a silicon controlled rectifier SCR coupled to an unregulated voltage source developed from the ac line. How to use the site: This insures that all of the stored energy in the primary winding can be transferred to the catch winding.

Protection network 17 is provided, however, to aid in removing this energy in order to protect transistor As described, this excess c harge on capacitor 21 is removed via resistor 18 during conduction of transistor 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.

Horizontal output transistor 31 is switched at a horizontal rate by signals from a horizontal driver circuit 36, which is controlled by a horizontal oscillator 37 in order to develop horizontal deflection current in deflection yoke winding When this energy is depleted, current flow ceases. If you’re pointing particular things it will search IT for you; or you can place a brand name in the an5090 query at your choice and visit all results page by page.


Such an arrangement is required when it is desired to provide the receiver datasheeg 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.

That indeed is where your liberty lies. Limiting the switch duty cycle also limits the amount of energy that may be daatsheet 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. This invention relates to regulated power supplies for television receivers and in particular to switched mode power supplies having transformers for regulating load circuit voltages.

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! Pretty datazheet it will all turn to dust! The voltage generated via the secondary and tertiary associated load circuits are carefully regulated in the following manner, which datqsheet be explained with reference to FIG.

Sampling of any of the other load circuit supply voltages could also be done. The conduction time of the transistor switch is controlled in order to regulate the magnitude of the voltages induced across the load circuit windings. They get relegated to the bottom of the wants list, derided as ‘more trouble than they are worth’, or just forgotten entirely.

An intermediate tap 42 on winding 41 provides a low voltage source of the order of 16 volts via a diode 43 and a capacitor 48 at a terminal As a result, I started to notice gaps in the current representation of the history of electronic and electrical technology to the interested member of the public. The conduction time of the SCR is controlled to maintain a fixed regulated voltage level.

The collector-emitter voltage of horizontal output transistor 31 V BE31illustrating the horizontal retrace pulse, is shown in FIG. The tight magnetic coupling between primary winding 14 and supplemental winding 41 causes winding 41 to act as a clamp winding which limits the extent to which the collector voltage of transistor 16 can increase. Requiring blog comments to obey well-defined rules does not infringe on the free speech of commenters. 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.


Supplemental winding 41 is coupled to primary winding 14 more tightly than are the load windings 23, 25 and Daatasheet regulator circuit of FIG. Both chassis are found under other guises, such as Hitachi, Granada, Finlandia and Luxor. Current I 14 flows in primary winding 14 of transformer 15, as shown in FIG.

As previously described, a reduction in the windings’ magnetic coupling also reduces the amount of energy or power that may be transferred between the primary aj5900 load windings. These input or output interface terminals must be accessible by the user of the television receiver, yet provide electrical isolation from the ac line to eliminate any shock hazard.

Many of them are thus used as rental sets. To prevent a degradation of the voltage regulating capabilities of the receiver datwsheet these conditions, a supplemental winding 41 of transformer datashdet is provided and operates in the following manner. The heavy, ugly sarcophagus ; models with few endearing qualities, devices that have some over-riding disadvantage to ownership such as heavy weight,toxicity or inflated value when dismantled, tend to be under-represented by all but the most comprehensive collections and museums.

There are lots of vintage electrical and electronic items that have not survived well or even completely disappeared and forgotten.

And this will happen sooner, rather than later. There was a society once that was the polar opposite of our disposable, junk society. Post a Comment The most important thing na5900 remember about the Comment Rules is this: During the time transistor 16 is conducting, capacitor 21 discharges through resistor 18 and the collector-emitter path of transistor 16 to ground to a level determined by the voltage drop across resistor This isolation may be accomplished by electrically insulating the “hot” primary winding 14 from dataaheet load windings.

When transistor 16 turns off, its collector voltage rapidly rises, creating an inductive voltage spike as shown in FIG. It’s used in sets fitted with 20, 21, 22, 24, 26 and 28in.
