Abstract

Regulatory device-electronic circuit breaker perfected especially for the control and regulation of the excitation in dynamos and alternators, characterized essentially by using an electronic circuit to transistors that includes a conventional differential amplifier system, combined with a "darlingthon" circuit of amplification in chain, said differential amplifier is constituted by a first transistor, whose collector is connected to a terminal of positive connection of the generator or dynamo, while its base is connected through a diode has the cursor of a variable resistance, one of whose ends is connected to the collector of the first transistor through a fixed resistor, there also being a fixed capacitor connected between collector and base, while the opposite end of said variable resistor is connected, through a second fixed resistor, to a mass connection or negative of the power supply to be charged, from where a third fixed resistor is connected to the emitter of the first transistor, this emitter being connected to the base of a first transistor of the "darlingthon" circuit or second transistor of the regulator circuit, which presents its collector also connected to the positive terminal of the generator or dynamo, while its emitter is connected to the base of a third transistor that also has its collector connected to the positive terminal of the generator or dynamo, while its the transmitter is connected to a second terminal for the connection of the excitation coil of said generator or dynamo, said emitter of the third transistor being connected, through a fourth fixed resistor, with said ground or negative connection of the source of the transistor. Feeder to be charged, between whose mass connection and said second terminal of the excitation coil connection a rectifier diode is connected to the generator or dynamo, the regulator circuit finally comprising a second fixed capacitor connected between the positive terminal of the generator or dynamo and the ground or negative connection of the power supply to be charged, in such a way that that said regulating circuit disposed between said first connection terminal of the generator positive and, the ground or negative connection of the power supply to be charged, achieves a constant voltage in the second connection terminal of the positive of the excitation coil, by means of which results in a constant voltage output from the generator.
