SCIENTEK ELECTRICAL has produced a generator voltage regulator, which consists of a triode, a triode connected in series to its emitter, a Zener diode, etc. to form its unique fast emitter coupling transient steady-state trigger circuit with temperature compensation to realize the regulation circuit The rapid conversion, temperature compensation and proper adjustment of the conversion frequency, so that it can work stably under harsh environmental conditions.
Provide a generator voltage regulator suitable for battery charging with a low power consumption of the regulator itself, and the regulator's regulating voltage value changes with the change of the ambient temperature around the regulator, and can automatically adjust its voltage value according to the ambient temperature change, Effectively solve the problem of the thermal breakdown of traditional voltage regulators.
Since the Zener diode has a certain voltage regulation range and the leakage current will increase as the temperature rises, the speed of the regulating circuit will decrease, that is, the cutting off and connection of the magnetic field circuit is not rapid; the pulse voltage of the magnetic field circuit The rising and falling edges of the waveform are not steep; the power transistors in the circuit work in the amplification area for a long time, and the dissipation power is relatively large.
In addition, the working environment of the generator voltage regulator is harsh, especially the built-in regulator, which works at high temperatures In the engine room, the ambient temperature is high, and the temperature of a cold car is very different from that of a hot car. Therefore, it is prone to the instability of the regulating voltage and thermal breakdown to make the regulator fail.
SCIENTEK ELECTRICAL's AC generator voltage stabilizer has strong versatility, stable and reliable performance, and can adapt to harsh working environments. The regulating circuit itself has low power consumption and small size and can be adapted to be installed separately or integrated with the alternator at the same time.
It can automatically adjust the set voltage value of the regulator with the change of the external environment temperature, so as to be suitable for battery charging under environmental conditions. If necessary, the voltage control and measurement method in the prior art is changed.
Parameter-adjustable voltage stabilizer, suitable for departments with special requirements for reliability and anti-interference performance(solid state voltage regulator). Parameter adjustable voltage stabilizer has high reliability; anti-high-energy interference; no output over-voltage phenomenon; wide input voltage range; good overload performance (strong overload capability of ferromagnetic components); it can be made into high-power power supply equipment.
An automatic voltage regulator is suitable for departments that do not require response time. Wide input voltage range (using the characteristics of the long stroke of the brush); the output voltage waveform is the same as the input voltage waveform, and the phase is also the same; the efficiency of the whole machine is high (the loss of the self-made voltage regulator is small, the general efficiency is above 95); the nature of the load Good adaptability; easy to manufacture, low cost and low price; it can be made into a high-power compensation power supply.
Compensation regulator, suitable for making power regulators that do not require high load properties. Fast response speed (due to the use of power tubes as switching devices); can be made into high-power models; low output voltage distortion (no additional distortion in the machine); high efficiency.
