Description

(54) INVERTER

the diagonal of which is included a current-stabilized two-port 9 with a ballast resistor l .10 connected to the input terminal.

The voltage from the winding 6 of the transformer G enters the primary winding 7 of the switching transformer 2, the operating current of which is set and maintained by a constant current-stabilizing two-pole 9. When the switching transformer 2 is saturated, the resistance of the winding 7 drops sharply, however, during the core of the transformer 2 in a saturated state resistance totoxidizing bipolar. ka increases the total resistance of the circuit: winding 7; diode bridge 8, current-stabilized two-port 9 - remains unchanged. , , -.

& result — current surges in the primary winding 7 of the switching transformer 2 are eliminated, which increases efficiency and reliability. The converter is switched after the dissipation of the volume charge in transistors 3 or 4. The amplitude of the collector current and the dissolution time of the volume charge: directly proportional to the current without switching transistors 3.4.

Since the current pulse in the winding 7 is eliminated in the converter, the currents of the bases of the transistors 3, 4 before switching (; are lowered, as a result of which the transistors 3,4 switch to the output mode rtph less than the saturation factor.

this limits the discharge of the collector1;
