<p>1. Power transistor converter with anti-shorting protection for converting direct current into alternating current, containing a control system, push-pull power amplifier and output transformer characterised in that the output transformer (TR) possesses additional winding (Z3) connected, with the use of the rectifier (PR) and filter (F), to collectors of the pair of npn transistors (T3 and T4), and the collectors of transistors are connected, with the use of the start-up resistor (R), to a positive pole of power source (B), and simultaneously, the collectors of transistors are controlled with the control system (S) of the converter and bases, which are, in a push-pull manner and with the use of collectors, connected to the primary winding (Z1) of the output transformer (TR), npn transistors (T1 and T2), the emitters of which are connected to the circuit's ground connected to a negative pole of power source (B), and the positive pole of the source (B) is also connected to the centre tap of the output transformer's (TR) primary winding (Z1).<IMAGE></p> |
