Description

one

A pulsed-pulse device for controlling the voltage of an alternator, consisting of a stable pulse generator connected to a three-phase trigger meter and a matching circuit, a sensor converter, to which two inverters coincide with inverters, level reducers and actuator is known. organ.

To improve the quality of control and increase the reliability of the proposed device, the OUTPUT of the pulse generator is connected to the counter input and one of the inputs of the coincidence circuit, the other inputs of which are connected to the single outputs of the first two counter triggers and the zero output of the third trigger, and its output is connected to the sync | ron | izatsii sensor converter. The main input of the latter is connected to the phases of the adjustable oscillator, and the output to the input of the second coincidence circuit and through the inverter to the input of the third coincidence circuit. The other inputs of these coincidence circuits are connected respectively via an inverter and directly to the unit output of the counter, and their outputs through level reducing agents are connected to the inputs of the actuator.

FIG. 1 shows a functional diagram of the described device; in fig. 2 - timing charts of the device.

The device contains a highly stable generator (pulses), triggers 2-4, coincidence circuit 5, sensor preo (dialer 6, inverters 7 and 8, coincidence circuits 9 and 10, level 11 and 12 reducers, and actuator 13. a - generator pulses bd - pulses at the outputs of flip-flops 2-4, respectively, g - pulses of syncronization at the output of circuit 5, e - pulse-modulated sensor pulses, g - setpoint pulses, 3 inverted sensor pulses, and k - yn equalizer no impulses.

Generator 1, a three-digit counter on triggers 2-4, and a coincidence circuit 5, the inputs of which are connected to the single outputs of the flip-flops, are used to receive pulses for synchronization and pulses and setpoints. A circuit 5 is connected to one of the inputs of the transducer sensor 6, which consists of the known devices for converting alternating voltage into a proportional dependent direct voltage (voltage sensor) and constant voltage at a proportional dependent time interval. The outputs of the transducer transducer 6 and trigger 4 are connected to the inputs of inverters 7 and 5 and circuits 9 and 10, the coincidences, and the outputs of circuits 9 and 10 through level reducing agents // and 12 to the inputs of the actuator 13. Level reducing elements are matching elements between the circuits coincidence and executive body.

With an increase in alternating voltage from the output of the sensor-converter 6 software, the duration is longer than the pulse setpoint. The signals at the inputs of the circuit 9 are interleaved, and the output of this circuit is pulses, which through the reducing agent yipOBiHH 11 affect the actuator 13 so that the voltage of the generator 14 decreases. When the alternating voltage decreases, the pulses from the output of the transducer transducer are less in duration than the fading pulses. The signals are overridden at the inputs of the circuit 10 are identical. The pulses from the output of the circuit 10 through the reductant level 12 affect the executive body 13 1 and cause an increase in the variable voltage.
