It is a high-performance power electronic device with an asymmetric structure, high operating voltage and current, suitable for various power conversion and energy transfer applications, and can be used to adjust the speed and torque of motors, achieving precise motor control. Some opinions also believe that it belongs to the control pulse card module, which can be used to generate and control pulse signals. It has a multi-channel design, can control multiple devices simultaneously, can be configured through software programming, and supports VME bus interface, which is compatible with other VME devices
Description
ABB 3BHE023784 (control board/driver board category)
1. Basic positioning
Product ownership: Control board/driver board for ABB medium voltage frequency converters (such as ACS1000/ACS2000 series), responsible for driving signal processing and status feedback of power modules (such as IGCT modules).
Application scenario: High voltage motor speed control system (in industrial fields such as metallurgy, power, chemical industry, etc.), serving as the core control unit of the frequency converter, connecting the main control system and power devices.
2. Key parameters (typical values, subject to official standards)
Signal interface:
Support communication bus with the main control unit of the frequency converter (such as ABB customized high-speed bus), transmitting signals such as drive pulses, fault diagnosis, temperature/voltage feedback, etc.
Includes IGCT drive signal output channel (compatible with 5SHY series IGCT modules), with overcurrent, overvoltage, and undervoltage protection logic.
Working power supply: usually DC low voltage (such as+15V,+5V, etc.), which needs to be powered from the frequency converter power module to meet the power supply requirements of the control circuit.
Environmental adaptation:
Working temperature: -25 ℃~+70 ℃ (industrial grade wide temperature design, subject to actual heat dissipation conditions).
Protection level: IP20 (to be installed inside the inverter control cabinet, relying on cabinet protection).
3. Functional characteristics
IGCT Precision Drive: Output synchronous pulse signals to control the on/off of 5SHY series IGCT modules, ensuring stable operation of the inverter power unit.
Fault diagnosis: Real time monitoring of IGCT module status (such as temperature, current, voltage), quickly blocking the drive signal and reporting to the main control system when a fault is triggered.
Redundancy design: Some application scenarios support hot standby redundancy to improve the reliability of the inverter system.
