Do you really understand the series regulator?

In the 50s and 60s, people were keen on series regulators. From simple Zener diodes plus resistors to high-power manifolds.

However, the leakage of the manifold is severe, so a lot of compensation components are added to the circuit. However, it is still impossible to completely change the voltage drift over a long period of time and at high temperatures.

Although the pressure drop of the silicon tube is considered to be large, its high-impedance characteristics and stability have once again attracted attention. Therefore, the subsequent adjustment tubes are almost all silicon tubes.

Although the characteristics of the drift have been greatly improved, it still cannot change its power consumption, and the heating of the adjusting tube is serious, so people have come up with a voltage regulator circuit of the thyristor. Its circuit has been popular for a while. Even many color TV power supplies use a thyristor voltage regulator circuit.

However, the thyristor is still in series, the heat is still large, and the speed is not high. But performance has improved a lot.

Research is still going on. Later, an integrated series regulator was developed. The performance is further improved, and the integration is used, and the peripheral circuits are extremely simple, which has been sought after for a while.

This integrated regulated output has three forms, old-fashioned, intermediate, and low-saturation. Their voltage drops are 1.7V, 1V, and 0.3V, respectively.

But the above can not get rid of a weakness, that is, the output voltage can only be less than the input voltage. If for some reason the input voltage is lower than the output voltage, the device may not work properly. What?

Can you develop a voltage regulator that maintains a stable voltage output even if the input voltage is lower than the output voltage? People are thinking!

KNB6-63 Miniature Circuit Breaker

KNB6-63 Mini Circuit breakers, also named as the air switch which have a short for arc extinguishing device. It is a switch role, and also is a automatic protection of low-voltage electrical distribution. Its role is equivalent to the combination of switch. Fuse. Thermal Relay and other electrical components. It mainly used for short circuit and overload protection. Generally, According to the poles, mini Circuit breaker can be divided into 1P , 1P+N , 2P, 3P and 4P.
