Overview of Thyristor/Diode Module (Non-Isolated Type)

Thyristor/diode modules (non-isolated) are high-voltage, high-current, and fast-responsive electronic devices composed of thyristors and diodes used in power electronics and industrial automation. The structure includes a thyristor chip, a heat sink, and an insulating substrate. Current control is achieved by controlling the triggering voltage and current of the thyristor. Non-isolated designs require attention to safety and heat dissipation. Compared with other modules, it has the advantages of high voltage, high current, and fast response but requires high requirements for non-isolation and heat dissipation.

FAQ

Q1

How do you correctly select and use thyristor/diode modules (non-isolated) to meet specific power control needs?

Re:When selecting a thyristor/diode module (non-isolated type), specific requirements for power control, such as voltage, current range, frequency response, etc., need to be considered. Ensure that the selected module meets these requirements and evaluate its stability, reliability, and heat dissipation performance. When using, the manufacturer's recommended operating conditions should be followed, including control of trigger voltage and current, as well as heat dissipation measures. In addition, attention should be paid to the installation and connection of modules to ensure safety and stability.

Q2

How does a thyristor/diode module (non-isolated type) manage heat during operation to ensure its stability and reliability?

Re:Thermal management is crucial to ensuring the stability and reliability of thyristor/diode modules. Appropriate heat sinks should be selected to provide sufficient heat dissipation area and close contact with the module. Meanwhile, the working environment should be well-ventilated to avoid high temperatures and humidity. In addition, by controlling the operating temperature and current of the module, heat generation can be reduced, thereby improving its stability and reliability.

Q3

How are the triggering voltage and current of thyristor/diode modules (non-isolated) controlled?

Re:The triggering voltage and current of the thyristor/diode module are controlled through external circuits and controllers. Usually, trigger circuits provide appropriate trigger signals, such as pulse signals or DC signals, to maintain the conduction and disconnection of thyristors. The controller is responsible for monitoring and adjusting trigger signals to meet specific power control requirements.

Q4

What safety hazards does the non-isolated design of thyristor/diode modules (non-isolated) bring?

Re:Non-isolated thyristor/diode modules may pose safety hazards, such as the risk of electric shock and short circuits. Due to the lack of isolation in the internal circuits of the module, when external circuits malfunction or operate, it may cause current leakage or short circuit, which can damage the module or cause personal injury. Therefore, when using non-isolated modules, special attention should be paid to safety measures, such as taking appropriate isolation measures, using insulation tools, etc.

Q5

What are the advantages and disadvantages of thyristor/diode modules (non-isolated) compared to other types of power electronics modules?

Re:The advantages of thyristor/diode modules (non-isolated) lie in their high voltage, high current, and fast response capabilities, making them particularly suitable for power electronics applications that require efficient control and regulation. In addition, its simple structure and low cost are also one of its advantages. However, non-isolated designs may pose safety hazards and have high requirements for heat dissipation. Compared to other types of power electronic modules, such as isolated modules or PWM controllers, non-remote modules may be slightly inferior in terms of safety, stability, and control accuracy.
