ABB 5SHY3545L0003 is an IGCT module, and the following is a detailed introduction to it:
Structural Features: The 5SHY3545L0003 IGCT module is a press-fit device that requires a relatively high force to press onto the heat sink, which also serves as the electrical contact for the power terminal. This design aids in heat dissipation and ensures stability in electrical connections.
Control characteristics: The on/off control unit of this module is an integral part of the component, requiring only an external power supply. Its control functions can be easily accessed through a fiber optic connection. Its control power consumption is typically between 10-100W, with a typical on/off switching frequency of around 500Hz, and it can achieve short switching pulse trains with a switching frequency up to 40kHz.
Performance Advantages: The IGCT module is optimized for low conduction loss, combining the advantages of hard-driven GTO thyristors and improving the turn-off performance. Uniform switching enhances the safe operating region of IGCT, reaching the dynamic avalanche limit, eliminating the need for snubber circuits, and allowing high-frequency applications to be extended to the kHz range.
Application Scope: The new series of IGCT devices with integrated high-power diodes is suitable for applications within the range of 0.5–6MVA, and can be scaled up to several 100MVA through series and parallel connections. 100-MVA transformers based on IGCTs have been put into commercial operation, and this module is also applied in fields such as ABB’s new ACS1000 drive for medium-voltage applications.
Installation precautions: When installing the module, press-fit tools of different specifications such as the PFCL 201C series may be used to provide appropriate pressure. Additionally, during the installation process, care should be taken to prevent the module from being damaged by excessive voltage or current, ensuring its correct insertion and connection.
