VVZB135-16NO1 Discrete Semiconductor Products

Introduction to Thyristors - SCRs - Modules

The thyristors are very common components used in electronics. They are used in many applications, from consumer electronics and industrial machinery to consumer appliances. Thyristors can provide protection from voltage or current problems. The SCR (silicon controlled rectifier) is a specific type of thyristor that is used for more signal control applications.

A thyristor is a type of semiconductor component that is used to control the flow of electricity within an electrical circuit.It has three terminals, an anode, a cathode and a control terminal commonly referred to as the gate. When the chip is switched off, its gate is not connected to the external circuit and therefore no current flows. When the gate voltage is increased beyond its firing voltage, the thyristor will suddenly switch on and the entire current will flow through it. When the gate voltage is reduced to a certain level, it will switch off again.

The VVZB135-16NO1 is a specific type of thyristor module which is designed for higher power applications. It is a three-phase, bridge-style module and is capable of handling up to 1800V of alternating current. It is used in a wide range of applications, such as motor control, power conversion, rectification, and switching.

VVZB135-16NO1 Application Field

The VVZB135-16NO1 module is used in many different industrial and commercial applications. It is found commonly in motor controllers, power converters and rectifiers, allowing smooth and precise control of electric motors or other large loads. The precise and continuous control that it provides makes it ideal for applications such as motor speed control, motor torque control, motor speed regulation and motor start/stop control.

It is also used in power conversion, rectification and switching for applications such as lighting, heating, automation and even automotive applications. In addition to these industrial applications, the VVZB135-16NO1 is also used in consumer appliances such as washing machines and other high-power electrical equipment.

VVZB135-16NO1 Working Principle

The working principle of the VVZB135-16NO1 module is based on an AC to DC conversion circuit. This circuit consists of two thyristors, also known as thyristor gates, that act as a switch. When the gate is not triggered, the current will not flow through the module. When the gate is triggered, the current will flow through the circuit. This process is repeated with each cycle of the AC waveform.

The VVZB135-16NO1 module also incorporates additional circuitry such as a phase-angle controller and a dynamic brake to control the power flow within the circuit. This ensures that the module is capable of producing a steady direct current and avoids sudden changes in voltage or current. In addition, the dynamic brake allows the module to function as a chopper, allowing it to rapidly reduce the power flow when required.

Conclusion

The VVZB135-16NO1 is a specific type of thyristor module that is used for a wide range of applications. It is used primarily for motor control, power conversion, rectification, and switching, for both consumer and industrial applications. In addition, the working principle of the VVZB135-16NO1 involves an AC to DC conversion, with the added circuitry being used to ensure a steady direct current output.
