Adjustable High Voltage Power Supply 0 to 1000V

Adjustable High voltage power supply

To supply the high voltage converter suitable source of alternating voltage 12 V / 800 mA. An alternating voltage is rectified by a diode bridge with an allowable current of 1 A. Converter output voltage is adjustable between 0 … 1000 V. The scheme of the device is assembled on the step-up transformer, and such active ingredients as the timer 555, CMOS logic 4001, a voltage regulator 7805 , two NPN transistor conduction and a pair of field effect transistors IRF510 as powerful terminal keys.

The principle of operation of this scheme is no different from similar circuitry in the converters. A feature of this scheme is the high output voltage and the possibility of regulation.

If the transformer is shown in the diagram is missing, you can use any similar with the same transformation ratio. In this case, you need to pick up the frequency conversion to increase the efficiency of the device.

Power supply is an electronic device that supplies electric energy to an electrical load. The primary function of a power supply is to convert one form of electrical energy to another and, as a result, power supplies are sometimes referred to as electric power converters. Some power supplies are discrete, stand-alone devices, whereas others are built into larger devices along with their loads. Examples of the latter include power supplies found in desktop computers and consumer electronics devices.

      The diagram shows them to be LM338. If you look up the top you will see that just the power supply & ground pins are shown with IC3 LM338 & then scattered around the diagram are the internal circuitry blocks.

      Sometimes you will find the ground & supply pins not shown & occasionally you will find a separate circuit diagram or part of the diagram just showing all supply & ground pin connections.
