PULSE GENERATOR Russian patent published in 1999 - IPC

FIELD: electronic engineering. SUBSTANCE: generator has input of its inverter 1 connected to first lead of choke coil 7, emitters of transistors 5,6, and to input of inverter 2 whose output is connected through resistor 9 to second lead of choke coil 7 and to bases of transistors 5, 6. First input of EXCLUSIVE OR gate is connected to collector of transistor 5 and through resistor 8, to bus 12; its second input is connected to collector of transistor 6 and through resistor 10, to bus 13; its output is connected to first input of EXCLUSIVE OR gate 4 whose second input is connected to output of inverter 2 and output, to input of inverter 1 through integrating RC circuit 11. All these arrangements provide for eliminating frequency dependence on supply voltage and for limiting inrush current amplitude when magnetic circuit is saturating. EFFECT: reduced power requirement, provision for eliminating noise at inverter outputs and power circuits and overcurrent operation of inverter transistors. 1 dwg
