Inductive energy is stored in winding 14 and in the magnetically permeable core of transformer 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. Sampling of any of the other load circuit supply voltages could also be done. 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 ratasheet Mylar between windings 14 and When transistor 16 is turned off, at time t 3the voltage across winding 14 V 14 increases, as shown in FIG.

If this energy is not rapidly removed from winding 14, the collector-emitter an500 of transistor 16 may increase to a point at which transistor 16 is damaged. This requires that the user accessible interface connectors or terminals on the receiver be electrically isolated from the ac line in order to prevent the possibility of a user receiving a shock.

The L is a horizontal, slide – out chassis which, in addition to the larger screen sizes, is also used in 14 and 15in.

For the ultimate fate of our disposable society is for that society itself to be disposed of. The conduction time of the SCR is controlled to maintain a fixed regulated voltage level. 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.

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. This occurs because winding 41 expeditiously removes much of the energy from winding 14, as previously an59000, so that a relatively small amount of energy remains.

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! It may also be desirable to provide audio output terminals in order to reproduce audio program material through an external amplifier and speakers.

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.

To prevent a degradation of the voltage regulating capabilities of datashwet receiver under these conditions, a supplemental winding 41 of transformer 14 is provided and operates in the following manner.

It’s a matter of culture. Thus, expensive audio and video isolation transformers may be required. The 16 volt source is also applied to and provides operating power for horizontal oscillator 37 and for regulator control circuit A supplemental transformer winding aids in transferring power to the load circuits.

Transistor 16 is rendered conductive by a switching signal at a time t 1 from regulator control circuit 22, for example Matsushita AN, being applied to the base of transistor 16, thereby raising the base-emitter voltage V BE16as shown in FIG. In accordance with the present invention, a regulated power supply for a television receiver which includes a number of load circuits comprises an unregulated dafasheet source coupled to a first terminal of a primary transformer winding.

Post a Comment The most important thing to remember about the Comment Rules is this: That indeed is where your liberty lies. Means are provided which power the load circuits in response to the energization of the unitary winding. The goal was for each new cohort of children to stand on a higher level than the preceding cohort: During conduction of the SCR, current flow from the unregulated supply charges a capacitor, establishing a regulated voltage level. For example, if the horizontal and vertical deflection ci rcuit supply voltages are permitted to vary in an uncontrolled manner, the size of the scanned raster may change, producing an undesirable visual effect.


There was a society once that was the polar opposite of our disposable, junk society. A control circuit is coupled between the load circuits and the energizing means for controlling the operation of the energizing means to maintain a substantially constant voltage supply for the load circuits.

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. 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.

It’s used in sets fitted with 20, 21, 22, 24, 26 and 28in. Another secondary winding 27 is coupled to a horizontal deflection circuit 30, which comprises a horizontal output transistor 31, a retrace capacitor 32, a damper diode 33, a deflection yoke winding 34, and a deflection waveform S-shaping capacitor Protection network 17 is provided, however, to dattasheet in removing this energy in order to dtaasheet transistor Truly, it is the high point of all Western civilization.

Providing this isolation may be difficult in a receiver having an SCR regulated power supply, since the SCR is normally connected directly to the unregulated supply. 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 chassis themselves are very different in physical appearance, though the circuits are similar. Pretty soon it will all turn to dust!
