Thyristors, also called SCR (silicon controlled rectifier) are a form of electrical switch suitable for an alternating current (AC). The main type of thyristor is the TRIAC, which controls the current for both directions. The AVS112CB is a type of TRIAC which is used for various applications, with a special focus on load switching operations.

The TRIAC is a 3-terminal electronic component consisting of two thyristors connected in anti-parallel, transistor like configuration. The main advantages of the AVS112CB TRIAC are its fast switching speed, low on-state voltage drop, and its ability to handle high voltages.

The most common application of the AVS112CB TRIAC is in power supplies. It is used to control the voltage output, as well as the current output, of a power supply. It is capable of switching input and output voltages of up to 1000V and output current of up to 10A, which makes it suitable for a wide range of applications, such as home appliances, industrial machinery, and medical equipment. It can also be used in motor speed control, phase control units, and switching circuits.

In terms of its working principle, the AVS112CB TRIAC employs a circuits control system known as the buck boost method. This method works by adjusting the output voltage with the use of a feedback loop that adjusts the on-off states of its switching transistors. The AVS112CB TRIAC is capable of delivering a constant current output regardless of whether the current load is increasing or decreasing.

The AVS112CB TRIAC also has a load-switching circuit to control the load current. The load switching circuit works by monitoring the voltage drop across the thyristor to determine when to begin switching the current. Once the switching point is reached, the voltage applied to the thyristor is lowered, a process that is known as “robbing”. This process allows the TRIAC to switch off the current while still maintaining the desired current level.

Lastly, the AVS112CB TRIAC is also capable of monitoring its own temperature, which is necessary for its safe operation. When the temperature of the TRIAC exceeds its predetermined temperature threshold, the TRIAC automatically shuts off. This protective feature ensures that the TRIAC will not be damaged by running for too long or under excessive current loads.

In conclusion, the AVS112CB TRIAC is an excellent choice for various power supply, load switching, and motor speed control applications due to its fast switching speed, low on-state voltage drop, and its ability to handle high voltages. Its buck boost method of voltage control and load switching circuit help to ensure a safe and consistent operation. Lastly, its onboard temperature monitoring system helps to protect the TRIAC from any possible damage.
