Abstract

The transformer is used as a supply source for digital-programmatic control of metal-cutting machines, and in electric equipment. It consists of two secondary windings (3 and 4) of a driver transformer (5), a winding of a current transformer (10), a source of constant voltage, while the one end of the outlet of a condenser (12) is connected to the minus outlet of the source and the end of a current transformer winding. The anode of a diode (14) is connected to the end of the primary winding (6) of an impulse transformer (7), while its beginning is connected to the cathode of a diode (8). The beginning of the driver transformer's winding is connected to the anode of a diode (8), the source of a transistor (2), the anode of a diode (9), while its other outlet is connected to one end of a resistor (13). Its other end is connected to the transistor gate and the cathode of a diode. The start of the secondary winding (4) of the driver transformer is connected to the anode of a diode (15), the source of a transistor (1), to one outlet of a condenser (16), the cathode of a diode and to the beginning of a primary winding (6) of the impulse transformer. The end of the same winding is connected to the anode of a diode, to the one end of a resistor (17) and the drain of the transistor. One end of the second winding of the driver transformer is connected to a resistor (18), and its other end - to the cathode of a diode and the gate of the transistor. The second outlet of the condenser is connected to the second outlet of the resistor. Another resistor (11) and condenser are connected parallel to the source of constant voltage. The drain of the transistor is connected to the positive pole of the source for constant voltage.
