FIELD: radio engineering. ^ SUBSTANCE: impulse stabilizer contains serial adjusting p-n-p transistor, control block, LCD-filter, connected to output clamps of stabilizer and to collector of adjusting p-n-p transistor, first resistor, connected by one clamp to input clamp of stabilizer, by another clamp - to emitter of adjusting p-n-p transistor. Input clamp is connected to emitter of protective p-n-p transistor, collector of which is connected to base of adjusting p-n-p transistor and to first output of second resistor composite p-n-p transistor is connected, base of which is connected to inverse output of control block and to input clamp through third resistor. Collector of composite p-n-p transistor is connected to second output of second resistor, emitter of which is connected to power input of control block. Impulse stabilizer also contains germanium diode of Schottky diode, anode of which is connected to emitter of adjusting p-n-p transistor, and cathode - to base of protective p-n-p transistor, and through resistor - to power input of control block. Control input of control block is connected to first clamp of check connection resistor, connected by second output to output positive clamp of stabilizer. Collector of composite p-n-p transistor through resistor is connected to first output of check connection resistor. ^ EFFECT: decreased voltage drop between input and output clamps of impulse stabilizer, great stability of output current, frequency and pulsations level. ^ 1 dwg |
