Compared with traditional two-level topologies, it delivers lower output harmonics and is more friendly to motor insulation. Its all-metal package combined with ceramic substrate heat dissipation technology effectively reduces thermal resistance and enhances vibration resistance, ensuring stable operation across a wide temperature range.

In industrial drive applications, 3BHB003689 works in conjunction with ABB’s Direct Torque Control (DTC) technology, achieving outstanding dynamic performance with speed step response ≤ 10 ms and speed regulation accuracy of ± 0.1%. Whether for precise speed control of high-power motors or in applications requiring accurate torque control such as winders and hoists, this module provides stable and reliable power conversion support.

Product Specifications

Structure and Composition

The ABB 3BHB003689 adopts a highly integrated modular design, combining advanced semiconductor technology with precision control circuitry. Its physical architecture consists of three main functional areas.

Power Semiconductor Switching Area forms the core power conversion section of the module, integrating high-performance IGCT chips. IGCT is the ideal power switch device developed by ABB specifically for medium-voltage drives. It integrates the GTO gate driver with the GTO into a single assembly, enabling the negative gate voltage to rise to the anode current amplitude within 1 μs, achieving extremely low turn-on and turn-off losses. The chip supports parallel connection of multiple chips to meet higher power requirements, with rated voltages up to 3300 V or higher and current ratings reaching hundreds to thousands of amperes. Power terminals are secured via bolt fastening or press-fit installation, ensuring reliable electrical connections under high-current conditions.

Gate Drive and Control Area is the intelligent signal processing core, consisting of a dedicated intelligent gate drive board. The drive board receives PWM pulse commands from the upper-level controller via fiber optics, providing comprehensive functions including electrical isolation, drive signal amplification, short-circuit protection, under-voltage lockout, and over-temperature monitoring. Built-in short-circuit protection and over-temperature detection functions provide real-time status feedback via LED indicators, and support parameter configuration and fault diagnosis through ABB DriveWindow debugging software.

Thermal and Enclosure Area features an all-metal package combined with ceramic substrate heat dissipation technology, effectively reducing thermal resistance and enhancing vibration resistance. The module measures 166 mm × 112 mm × 36 mm and weighs 1.3 kg, with a compact design facilitating high-density installation within power cabinets.

Key Features and Advantages

Superior Power Handling Capability
Utilizing advanced IGCT semiconductor technology, the module supports blocking voltages up to 12 kV and continuous currents up to 6000 A, with on-state resistance as low as 1.5 mΩ and switching frequencies up to 2 kHz. This enables 3BHB003689 to meet the high-power demands of large medium-voltage motor drives and power conversion applications.

Optimized System Compatibility
As a standardized component of ABB ACS series medium-voltage drives, 3BHB003689 seamlessly integrates with 5SHX series IGCT chips, 3BHL series driver boards, and system control units to build efficient and reliable power electronics solutions. It supports deep integration with ABB’s Direct Torque Control (DTC) technology, achieving superior dynamic response and speed regulation accuracy.

High Reliability and Wide Temperature Operation
The all-metal package combined with ceramic substrate heat dissipation technology, coupled with a wide operating temperature range of –40°C to +125°C, ensures long-term stable operation in harsh industrial environments such as metallurgy and mining. Built-in short-circuit protection and over-temperature detection provide real-time status feedback via LED indicators, enabling early fault warning and rapid diagnosis.

Simplified Installation and Maintenance
The modular design supports parallel connection of multiple chips to meet higher power requirements. Standardized interfaces and mounting methods (bolt fastening or press-fit) simplify system integration. The unique modular power unit design allows replacement of critical components without special tools within a short time, significantly reducing maintenance downtime.

Installation and Maintenance

Pre-installation Preparation
Before installing the ABB 3BHB003689, ensure that the drive power cabinet is completely de-energized and safely locked out. Operators must wear anti-static equipment and appropriate personal protective equipment, performing operations in a clean, dry environment. Before use, inspect the module for mechanical damage, oxidation or deformation of power terminals, and ensure fiber optic interfaces are clean and free from contamination. During installation, tighten power terminals strictly according to ABB-specified torque values to avoid excessive contact resistance causing overheating, or damage to the module body from over-tightening.

Maintenance Recommendations
Incorporate 3BHB003689 into the plant’s routine preventive maintenance schedule. During daily inspections, monitor the module’s operating status, temperature feedback, and fault records through the drive HMI, paying particular attention to critical parameters such as DC bus voltage and IGCT on-state voltage drop. It is recommended to perform dust removal on power cabinets, check power terminal torque, and visually inspect for signs of overheating discoloration or capacitor bulging on a semi-annual basis or according to the manufacturer’s recommended PM cycle.

Replacement Procedure
When replacing the module, strictly follow ABB-specified procedures and ESD protection requirements. Record the configuration parameters and positioning information of the existing module before removal. After replacement, perform parameter restoration and functional verification through DriveWindow debugging software. It is also recommended to inspect and clean the fiber optic connector end-faces of adjacent power assemblies to ensure control signal transmission quality. Spare units not in use for extended periods should be stored in anti-static packaging in a dry, dust-free environment with controlled temperature and humidity.
