Thyristors

Thyristors are devices that are widely used in commercial applications, power systems, and control circuits. They have several unique features that make them an ideal choice for many applications. The NP1100SBT3G is an integrated thyristor based rectifier control module that has been designed to provide a high degree of accuracy, flexibility, and efficiency for heavy industrial applications.

Application Field

As its name suggests, the NP1100SBT3G thyristor module is primarily used in applications related to rectifiers. Rectifiers are devices that are used to convert AC power to DC power. This thyristor module is well suited to heavy industrial applications that require high efficiency and a wide range of rectification performance. It is most commonly used in motor and generator control, heavy-duty power supply, HVAC, chemical industry, automotive, lighting, and other applications.

Working Principle

The NP1100SBT3G module consists of two thyristors that are connected in series. The thyristors are triggered by separate phase-sensing signals that control the conduction of current through the thyristors. When the phase-sensing signal is high, current flows through the thyristor, and when the phase-sensing signal is low, current does not flow through the thyristor. This allows for precise control of rectifier output. The thyristors themselves operate according to an on/off principle, meaning that the current flow can be triggered on or off in an instant.

In addition to providing precise control over the rectification process, the NP1100SBT3G module also features built-in protection features. These features include soft start protection, over-current protection, and temperature protection. The soft start protection feature prevents sudden surges of current, while the over-current and temperature protection features prevent the module from being damaged if it is exposed to excessively high levels of current or high temperatures.

The case design of the NP1100SBT3G module also offers superior protection against environmental hazards. The case is constructed from a high-grade aluminum alloy that provides superior protection against shock, vibration, and extreme temperatures. The case also features an epoxy seal to prevent moisture from entering the module and to protect it from dust and other contaminants.

The NP1100SBT3G is a highly reliable and accurate rectification control module that is widely used in various industrial applications. Its wide range of features, such as its built-in protection features, its superior case design, and its precise control capabilities, make it an ideal choice for many applications.
