This High voltage power supply can generate voltage of 5000 volts DC from 230 Vac line voltage . Its main purpose is the production of negative ions. (more…)
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
TP1 industrial design, a coil is designed for 220. 2 and 3 are designed for 12V, 2-I (upper diagram) is designed to return 10.8 A. TR 2 consists of a high-voltage winding (used in the factory with 800 coils), power coils containing 10.12 (chosen experimentally) and a feedback consisting of 28 turns, current transformer TP3 consists of a current of one coil winding and winding connection of 24 turns (to increase the sensitivity necessary to increase the number of
Stable power supply for high voltage power supply for the core of a high voltage of the PWM - Controller TL494, loaded with over 4050 followers on a pair of powerful field-effect transistors, switching the primary winding of step-up transformer (4 + 4 turns - the primary winding, 200 turns - the secondary winding). With the secondary winding through a rectifier with voltage doubling and smoothing filter RC LC voltage reaches the voltage divider, and the regulator output voltage.
