Description

Przedmiotem wynalazku jest zasilacz pradu stalego do zasilania lasera malej mocy.Znany zasilacz pradu stalego do zasilania lasera o malej mocy zbudowany jest z podwójnym ukladem zasilania. Jeden z ukladów zasilania indukuje podwyzszone napiecie wtórne zwane zaplonowym. Poniewaz do normalnej pracy lasera wymagane jest znacznie nizsze napiecie to z chwila pojawienia sie zaplonu uklad przelaczen wlacza do pracy drugi obwód zasilania o znacznie nizszym napieciu. Obwód ten indukuje w uzwojeniu wtórnym proporcjonalnie mniejsze napiecie wystarczajace do normalnej pracy lasera. W obwód uzwojenia wtórnego wlaczone sa elementy powielacza z których jest bezposrednie podlaczenie z odbiornikiem laserowym.W rozwiazaniu wedlug wynalazku obwód wtórny ^wspólpracujacy z pojedynczym obwodem zasilania pierwotnego ma kondensator szeregowo wlaczony z kondensatorami drugiej galezi obwodu. Zasilacz ma opornik wlaczony w obwód szeregowo wraz z kondensatorami.Zastosowanie rozwiazania wedlug wynalazku zwieksza stabilnosc zasilania lasera malej mocy przy pojedynczym obwodzie zasilania pierwotnego. Uklad polaczen uzwojenia wtórnego zmniejsza pulsacje ukladu zasilania.Przedmiot rozwiazania wedlug wynalazku jest przedstawiony w przykladzie wykonania na zalaczonym rysunku, na którym uwidoczniono budowe urzadzenia w ukladzie schematycznym. Transformator 1 zaopatrzo¬ ny w uzwojenie wtórne 2 ma pojedyncze uzwojenie pierwotne 3. Uzwojenie wtórne zaopatrzone w kondensatory Cl i C2 ma szeregowo wlaczony kondensator C5 oraz szeregowo polaczone diody D. Opornik R jest szeregowo polaczony z kondensatorami C3 i C4.Rozwiazanie wedlug wynalazku dziala nastepujaco: uzwojenie pierwotne 3 moze byc podlaczone do normalnej sieci zasilania elektrycznego 220 V 50 Hz.Po wlaczeniu do sieci i wytworzeniu sie napiecia w uzwojeniu wtórnym 2 nastapi ladowanie kondensato¬ rów Cl, C2, C3, C4 w kolejnych pólokresach napiecia zasilania przez diody D do szczytowego zwielokrotnionego2 108 538 ukladem. Z chwila powstania zaplonu na podlaczonym odbiorniku laserowym, maksymalne napiecie samoczyn¬ nie spada do napiecia zapewniajacego normalna prace lasera. Opornik R wlaczony w obwód szeregowo wraz z kondensatorami C3 iC4 tworzy filtr obnizajacy tetnienie napiecia w odbiorniku. Wielkoscia pojemnosci kondensatora C5 ustala sie moc wydzielana na obciazeniu, odbiornik laserowy i opornik R. Zastosowany uklad polaczen umozliwia podlaczenie dowolnego bieguna do przewodu zerowego.Zastrzezenie patentowe Zasilacz pradu stalego do zasilania lasera o malej mocy, znamienny tym, ze obwód wtórny (2) wspólpracujacy z pojedynczym obwodem zasilania (3) ma kondensator (C5) szeregowo wlaczony z kondensato¬ rem (Cl i C2) oraz opornik (R) wlaczony szeregowo z kondensatorami (C3 i C4).A C< D Cs £d d AD H<* + C5 +C4 Prac.

One of the power systems induces an increased secondary voltage, called the ignition voltage. Since a much lower voltage is required for normal laser operation, the moment an ignition occurs, the switching system switches on the second power supply circuit with a much lower voltage. This circuit induces a proportionally lower voltage in the secondary winding sufficient for normal laser operation. The secondary winding circuit includes multiplier elements which are directly connected to the laser receiver. In the solution according to the invention, the secondary circuit cooperating with a single primary power circuit has a capacitor connected in series with the capacitors of the second branch of the circuit. The power supply has a resistor connected in series with the capacitors. The use of the solution according to the invention increases the stability of the low-power laser supply with a single primary power supply circuit. The connection system of the secondary winding reduces the pulsation of the power system. The subject of the solution according to the invention is presented in the embodiment in the attached drawing, which shows the structure of the device in a schematic configuration. Transformer 1 provided with a secondary winding 2 has a single primary winding 3. The secondary winding provided with capacitors C1 and C2 has a capacitor C5 in series and diodes D connected in series. Resistor R is connected in series with capacitors C3 and C4. : the primary winding 3 can be connected to a normal 220 V 50 Hz power supply network. After switching on to the network and generating a voltage in the secondary winding 2, the capacitors Cl, C2, C3, C4 are charged in successive half-periods of the supply voltage through diodes D peak multiplied by the system. As soon as an ignition occurs on the connected laser receiver, the maximum voltage automatically drops to the voltage ensuring normal operation of the laser. The R resistor connected in series with the capacitors C3 and C4 forms a filter reducing the voltage ripple in the receiver. The capacitance of the C5 capacitor is determined by the power dissipated on the load, the laser receiver and the R resistor. The connection system used enables any pole to be connected to the neutral wire.
