Abstract
Układ rozruchowy przetwornicy impulsowej ma źródło prądowe (IS) połączone pierwszym zaciskiem z dodatnim zaciskiem napięcia zasilania (U ZAS) a drugim zaciskiem z dodatnim zaciskiem kondensatora napięcia pomocniczego (C1), katodą diody pierwszej (D1), wejściem zasilania układu sterującego (US) oraz wejściem detektora napięcia (DET). Wyjście detektora napięcia (DET) połączone jest z wejściem sterującym źródła prądowego (IS). Ujemny zacisk kondensatora napięcia pomocniczego (C1) połączony jest z masą strony pierwotnej przetwornicy. Anoda diody pierwszej (D1) połączona jest z jednym zaciskiem (3) uzwojenia pomocniczego transformatora impulsowego (TR) a drugi zacisk (4) tego uzwojenia połączony jest z masą strony pierwotnej przetwornicy. Pierwszy zacisk (1) uzwojenia pierwotnego transformatora impulsowego (TR) połączony jest z dodatnim zaciskiem napięcia zasilania (U ZAS), a drugi zacisk (2) z pierwszym zaciskiem (1) klucza półprzewodnikowego (Q), którego drugi zacisk (2) połączony jest z układem sterującym (US) a trzeci zacisk (3) połączony jest z masą strony pierwotnej przetwornicy. Jeden zacisk (5) uzwojenia wtórnego transformatora impulsowego (TR) połączony jest z anodą diody drugiej (D2), której katoda połączona jest z dodatnim zaciskiem kondensatora wyjściowego (C2) stanowiącego jednocześnie zacisk napięcia wyjściowego (U WY). Drugi zacisk (6) uzwojenia wtórnego transformatora impulsowego (TR) połączony jest z masą strony wtórnej przetwornicy, do której dołączony jest również ujemny zacisk kondensatora wyjściowego (C2).The starting system of the impulse converter has a current source (IS) connected via the first terminal to the positive terminal of the supply voltage (U ZAS) and the second terminal to the positive terminal of the auxiliary voltage capacitor (C1), the cathode of the first diode (D1), the power input of the control system (US) and voltage detector input (DET). The output of the voltage detector (DET) is connected to the control input of the current source (IS). The negative terminal of the auxiliary voltage capacitor (C1) is connected to the ground of the primary side of the converter. The anode of the first diode (D1) is connected to one terminal (3) of the auxiliary winding of the pulse transformer (TR) and the other terminal (4) of this winding is connected to the ground of the primary side of the converter. The first terminal (1) of the primary winding of the pulse transformer (TR) is connected to the positive terminal of the supply voltage (U ZAS), and the second terminal (2) to the first terminal (1) of the semiconductor key (Q), the second terminal (2) of which is connected with the control system (US) and the third terminal (3) is connected to the ground of the primary side of the converter. One terminal (5) of the secondary winding of the pulse transformer (TR) is connected to the anode of the second diode (D2), the cathode of which is connected to the positive terminal of the output capacitor (C2), which is also the output voltage terminal (U OUT). The second terminal (6) of the secondary winding of the pulse transformer (TR) is connected to the ground of the secondary side of the converter, to which the negative terminal of the output capacitor (C2) is also connected.
