Description

Устройство работает следующим образом. При положительной полуволне питающего напр жени  происходит зар д дополнительного кондепсатора Ci через неуправл емый вентиль Д до амплитудного значени  напр жени  питающей сети. При изменении пол рности сети на обратную таким же образом зар жаетс  другой дополнительный конденсатор Сд, но с обратной пол рностью. В это же врем  с блока управлени  БУ подаетс  отпирающий импульс на управл емый вентиль TI, который открываетс . Так как Ci , то дополнительный конденсатор С, разр жаетс  почти полностью через TI и импульсный трансформатор ИТ на рабочий конденсатор Ср. В следующий положительный полупериод питающего напр жени  снова происходит зар д дополнительного конденсатора С до амплитудного значени  напр жени  питающей сети. В течение этого полупериода питающего напр жени  подаетс  отпирающий импульс с блока управлени  БУ на управл емый вентиль Гд. Рабочий конденсатор Ср при этом перезар жаетс , в результате чего первична  обмотка импульсного трансформатора оказываетс  под воздействием напр жени , значение которого близко к удвоенному напр жению питающей сети. Импульсы напр жени , трансформиру сь из первичной обмоткн ИТ во вторичную, высоковольтную обмотку последнего, обеспечивают пробой и зажигание газоразр дной лампы Л. После того как лампа Л загорелась, зажигающее устройство отключаетс  и к питающей сети остаетс  подключенной только лампа Л. Видоизмененное устройство отличаетс  от основного наличием дроссел , включенного между выводом . сети и коммутатором. Оно позвол ет обеспечить подачу fia первичную обмотку импзльсного трансформатора ПТ почти учетверенного напр жени  питающей сети, так как дополнительные конденсаторы С и Сз в этом случае зар жаютс  до напр жени  близкого к удвоенному значению амплитуды напр жени  питани . Таким образом , при этом существенно улучшаютс  электрические параметры схемы устройства в целом за счет повышени  напр жени  на первичной обмотке импульсного трансформатора. Предмет изобретени  Устройство дл  питани  высокоинтенсивных источников света от сети переменного тока, содержащее импульсный трансформатор , первична  обмотка которого нодсоединена к сети переменного тока последовательно с рабочим конденсатором н коммутатором, а вторична  обмотка включена носледовательно с лампой, отличающеес  тем, что, с целью устранени  св зи разр дного контура источника высокоинтенсивного света с сетью н повышени  эксплуатационных характеристик устройства, коммутатор вынолнен в виде двух встречно-параллельных цепей, кажда  из которых состоит из включенных последовательно-согласно неуправл емого и управл емого вентилей, причем неуправл емые вентили упом нутых цепей подключены к одному из выводов сети переменного тока, управл емые - к рабочему конденсатору, а между общими точками управл емых и неуправл емых вентилей каждой из параллельных цепей включены два соединенных между собой последовательно дополнительных конденсатора , обща  точка которых соединена со вторым выводом сети переменнс11го тока.The device works as follows. In the case of a positive half-wave of the supply voltage, an additional condenser Ci is charged through an uncontrolled valve D to an amplitude value of the supply voltage. When the polarity of the network is reversed, another additional capacitor Cd is charged in the same way, but with reverse polarity. At the same time, a control pulse is supplied from the control unit CU to the control valve TI, which opens. Since Ci, the additional capacitor C is discharged almost completely through the TI and the pulse transformer IT to the working capacitor Cp. In the next positive half-period of the supply voltage, the additional capacitor C is charged again to the amplitude value of the supply voltage. During this half-period of the supply voltage, a trigger pulse is applied from the control unit of the control unit to the control valve Gd. The operating capacitor Cp is recharged in this case, as a result of which the primary winding of the pulse transformer is affected by a voltage whose value is close to twice the supply voltage. The voltage pulses, transformed from the primary IT winding to the secondary, high voltage winding of the latter, provide breakdown and ignition of the gas discharge lamp L. After lamp L has lit up, the ignition device is turned off and only L. lamp is connected to the mains. The modified device differs from the main presence of throttle, included between the output. network and switch. It allows the fia to be supplied with the primary winding of a PT impulse transformer of almost quadruple supply voltage, since the additional capacitors C and C3 in this case are charged to a voltage close to twice the amplitude of the supply voltage. Thus, this significantly improves the electrical parameters of the circuit of the device as a whole by increasing the voltage on the primary winding of the pulse transformer. Object of the Invention A device for supplying high-intensity light sources from an AC network, comprising a pulse transformer, the primary winding of which is connected to the AC network in series with a working capacitor and a switch, and the secondary winding is connected in series with a lamp, in order to eliminate communication the discharge circuit of a high-intensity light source with a network and an increase in the operational characteristics of the device, the switch is made in the form of two counter-parallel circuits, each of which consists of connected in series and according to uncontrolled and controlled valves, and uncontrolled valves of the above circuits are connected to one of the AC outlets, controlled - to the operating capacitor, and between common points of controlled and uncontrolled Each gate of each of the parallel circuits includes two additional capacitors connected in series, the common point of which is connected to the second output of the alternating current network.
