ABB 5SHX0660F0001 3BHB003387R0101 IGCT Module

1. Module Overview

5SHX0660F0001 IGCT Module

Category: This is a discontinued ABB IGCT (Integrated Gate Commutated Thyristor) communication system module, which is a high-voltage and high-power semiconductor device.

Applicable scenarios: Mainly used in petrochemical, power transmission, industrial drive and other fields, it can meet the application requirements of high voltage (such as 4.5kV) and high current (such as 3kA), and is suitable for bufferless operation scenarios with switching frequencies ranging from 500Hz to 2kHz.

Technical features: The "hard gate drive" technology can convert the thyristor from the latched state to the transistor mode within 1μs, eliminate the risk of latch-up, expand the safe operating area (SOA) to the dynamic avalanche limit, and reduce the conduction loss (compared to IGBT), achieving low-power stable operation.

Category: It can be used as a supporting component of the IGCT system, which may be a driver board or control card for DCS (distributed control system) or sensor interface.

Function: Provides 24V DC isolated power supply, supports backplane power supply, and is suitable for industrial control systems such as ABB's RX3i/IC695, ensuring stable power supply and signal transmission of the module in complex industrial environments.

2. Core Technology Advantages

High reliability: The GTO turn-off SOA of IGCT has been optimized, and with the help of coaxial gate feedthrough PCB design, the gate inductance is extremely low, and the turn-off di/dt can reach ≥5–6 kA/μs, which can adapt to harsh working conditions.

Low-loss operation: When turned on in thyristor mode, the conduction loss is lower than that of IGBT, and the switching loss is equivalent to that of IGBT (excluding IGBT diode recovery loss), which is suitable for megawatt-level energy conversion, such as motor drive, HVDC converter, etc.

Integrated design: Some modules integrate gate drive circuits (such as Abstract 4), simplifying system design, reducing external components, and reducing installation costs.

3. Application fields

Industrial drive: It can be used for large motor control in mining, rail transportation and other fields, such as hoists and traction systems.

Power system: Applicable to high-voltage inverters, static VAR compensators (SVCs), HVDC transmission, etc., for efficient power conversion and regulation.

Petrochemical and energy: Used for stable control of high-power equipment in petrochemicals and renewable energy (such as wind power converters).
