PULSE OSCILLATOR Russian patent published in 1994 - IPC

FIELD: pulse engineering. SUBSTANCE: oscillator has a circuit which comprises control switch, alternative resistor, winding of electromagnet relay, and capacitor connected in series. Common output of a winding of the electromagnet relay and capacitor is connected with anode of a diode and leads for connecting with a load. One output of a closing contact, which is made of a read relay, is connected with the common output of the capacitor, alternative resistor and control switch. The second alternative resistor is connected between cathode of the diode and output of the read relay used as a closing contact. The contact is coupled with the lead for connecting with the load. Movable contact of the alternative resistors are common. EFFECT: stabilized bearing voltage. 2 dwg
