STABILIZED CONVERTER OF CONSTANT VOLTAGE Russian patent published in 2004 - IPC

FIELD: electrical engineering.

SUBSTANCE: device has constant voltage source 1, which is connected to parametric voltage stabilizer 2, output of which is connected to power output of Schmidt trigger 3, inverse output of which through connected in series first resistor 4 and capacitor 5 is connected to another output of constant voltage source 1 and directly connected to controlling input of key 6, output of which is connected to first output of constant voltage source 1 through primary winding 8 of impulse transformer, which through connected in series respective rectifier 9 and filter 10 is connected to respective load 11, first diode 12, integrating RC-circuit 13, second diode 14, second and third resistors 15 and 16, at least, one voltage-reference tube 17. Additional secondary winding 18 of impulse transformer 7 is connected to anode of diode 12, cathode of which is connected to filtering capacitor 19 and through connected in series resistor 15 and, at least, one voltage-reference tube 17 is connected to input of Schmidt trigger 4 and to cathode of diode 14, anode of which is connected to output of integrating RC-circuit 13, input of which is connected to inverse output of Schmidt trigger 3, input of which is connected to point 20 through resistor 16, point 20 being a point of connection of resistor 4 and capacitor 5. Rectifier 9 is made on basis of bridge circuit.

EFFECT: simplified construction and stabilization of several output secondary voltages.
