In accordance with the present invention, a regulated power supply for a television receiver which includes a number of load circuits comprises an unregulated voltage source coupled to a first terminal of a primary transformer winding.

Additional receiver circuits may be subject to excessive electrical stresses or may be damaged if supply voltages are not held within acceptable limits. This in turn energizes the electrically isolated load circuit windings in order to power the associated load circuits. This isolation may be accomplished by electrically insulating the “hot” primary winding 14 from the load windings. The society that prioritized human, social and material quality is a Winner.

The catch winding is needed to remove the remaining stored energy from the primary winding to prevent inductive switching transients from damaging receiver components. The 16 volt source is also applied to and provides operating power for horizontal oscillator 37 and for regulator control circuit The chassis themselves are very different in physical appearance, though the circuits are similar.

Truly, it is the high point of all Western civilization. Current I 14 flows in primary winding 14 of transformer 15, as shown in FIG. 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.

This insures that all of the stored energy in the primary winding can be transferred to the catch winding. The other terminal of winding 14 is coupled to the collector of a transistor 16 and through a protection network 17, comprising a resistor 18, a diode 20 and a capacitor 21, to ground. An arrangement for electrically isolating the receiver load circuits from the ac line via the high voltage power transformer is disclosed in a copending application entitled “Regulated Power Supply Circuit”, Ser.

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. 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.

That indeed is where your liberty lies.

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. If you’re pointing particular things it will search IT for you; or you can place a brand name in the search query at your choice and visit all results page by page.

There was a society once that was the polar opposite of our disposable, junk society. As described, this excess c harge on capacitor 21 is removed via resistor 18 during conduction of transistor Fair people are getting fair reply. Resisting the tide of post-modernity may be difficult, but I will attempt it anyway.

Means are provided which power the load circuits in response to the energization of the unitary winding. How to use the site: All sets and apparates appearing here are property of Engineer Frank Sharp. One type of voltage regulating circuit utilizes a silicon controlled rectifier SCR coupled to an unregulated voltage source developed from the ac line. 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 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.

The bitterness of poor quality is remembered long after the sweetness of todays funny gadgets low price has faded from memory An intermediate tap 42 on winding 41 provides a low voltage source of the order an590 16 volts via a diode 43 and a capacitor 48 at a terminal Inductive energy is stored in winding 14 and in the magnetically permeable core of transformer datashest 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.

This attitude was reflected not only in the manufacturing of material goods, but also in the realms of art and architecture, as well as in the social fabric of everyday life. The conduction time of the SCR is controlled to maintain a fixed regulated voltage level.

The potential difference between primary a5900 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. 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 A control circuit is coupled between the load circuits sn5900 the energizing means for controlling the operation of the energizing means to maintain a datashete constant voltage supply for the load circuits.

Current flow in winding 41 may also be terminated by the switching of transistor 16 terminating conduction of winding Don’t forget the pastthe end of the world is upon us! Or are not being collected nowadays in proportion to their significance or prevalence in their heyday, this is bad and the main part of the death land.

It’s useful since the content of the site is very large. 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 In the interest of safety, guidelines and requirements may exist which define the amount of insulating material that is needed or the physical separation between windings, particularly between the high voltage ultor winding and the low voltage windings, that is required.

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. It’s used in sets fitted with 20, 21, 22, 24, 26 and 28in. The regulator circuit of FIG. Supplemental winding 41 is coupled to primary winding 14 more tightly than are the load windings 23, 25 and The amount of energy that 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.

Providing this isolation may be difficult datadheet a receiver having an SCR regulated power supply, since the SCR is normally connected directly to the unregulated supply. The previously described SCR regulated power supply is not economically incorporated in a receiver which provides input and output terminals electrically isolated from the ac line.
