Description

ABB 5SHY5045L0020

I. Basic Information

• Product Type: Integrated Gate-Commutated Thyristor (IGCT) power chip.
• Core Function: Performs high-voltage, high-current switching and power conversion as the power core of medium- and high-voltage power conversion systems. It features high voltage withstand capability and high current-carrying capacity, exhibiting low loss characteristics of a thyristor during conduction and stable turn‑off performance of a transistor during turn‑off. Trigger signals are typically transmitted via optical fibers; control requires only one power supply and two optical fibers. It operates stably without snubber circuits, enabling plug‑and‑play, simplifying system design and reducing failure points. It also realizes bidirectional AC‑DC energy conversion and supports four‑quadrant motor operation (motoring, braking, generating, plugging).
• 
  
• Application Positioning: Suitable for medium‑high voltage (3 kV–10 kV) and medium voltage (690 V–3.3 kV) high‑power power conversion. Mainly used in high‑voltage inverters and high‑power converters (e.g., phase modules in ABB ACS6000 series active rectifier units), matching power grid equipment and medium‑power industrial drives. Used with large synchronous generators, Static Var Compensators (SVC), STATCOM flexible AC transmission equipment, and HVDC converter valves. Typical applications include power, metallurgy, petrochemical, rail transit, and new energy industries, meeting variable frequency speed regulation requirements for fans, pumps, compressors, rolling mills, hoists, and other industrial equipment.

• Product Features: Compact size, high integration, powerful performance, excellent current conduction and voltage withstand capability; high electromagnetic immunity suitable for harsh industrial electromagnetic environments and complex working conditions. Modular design enables easy installation, maintenance, and system integration with seamless compatibility with dedicated ABB gate drive units without additional tuning. Imported original product with reliable quality, available domestically and overseas, with stock in some channels. Outstanding advantages include low conduction loss, high switching speed, and snubberless operation, high operational reliability, increased system power density, and ability to drive bidirectional loads.

II. Electrical Parameters

• Rated Voltage: Designed for medium‑high voltage applications, rated at 4500 V DC (or AC peak voltage), corresponding to medium‑voltage 690 V–3.3 kV systems. Stable high‑voltage blocking capability meets high‑voltage demands in power systems and medium‑high voltage drives. Integrated high‑voltage insulation allows direct connection to medium‑high voltage grids without external step‑down transformers, simplifying system design.
• 
  
• Rated On‑state Current (I_TAVM): Excellent current‑carrying capacity, with a typical continuous on‑state current of 2000 A and peak current exceeding 4000 A. Stably supports high‑power loads, matching requirements for medium‑high voltage high‑power converters and power grid equipment, suitable for 3‑phase 50/60 Hz operation and long‑term stable running.
• Switching Frequency: Designed for medium‑high frequency operation, typical switching frequency 1–3 kHz (standard for IGCT), up to 5 kHz. Fast switching with stable performance without snubber circuits greatly reduces switching losses, satisfying precise medium‑high voltage power conversion and meeting frequency requirements in industrial drives and power systems, with optimal performance in the 500 Hz–2 kHz range.
• 
  
• Switching Characteristics: Microsecond‑level turn‑on and turn‑off times. A hard gate drive can switch the thyristor from a pnpn latched state to pnp mode within 1 µs; turn‑off occurs entirely in transistor mode, eliminating latching. It withstands extremely high di/dt and du/dt, achieving ≥5–6 kA/µs at 20 V gate voltage. Snubberless design further reduces losses, improves overall system efficiency, ensures stable and reliable switching, and suits high‑frequency high‑power conditions.
• Protection Functions: Built‑in overcurrent, short‑circuit, over‑temperature, and overvoltage protection effectively prevents chip damage under abnormal conditions, resists external interference and faults, stops fault propagation, and ensures safe and stable operation. Comprehensive status monitoring provides real‑time feedback, fast fault location, and reduced downtime, meeting high‑reliability industrial system requirements.
• 
  
• On‑state Characteristics: Low on‑state voltage drop (1.5–2.5 V), inheriting the low loss advantage of thyristors, high conduction efficiency, low operating loss, and optimized energy consumption. System conversion efficiency exceeds 98%. Input/output characteristics match industrial control requirements, enabling flexible and precise control with gate drive units in various scenarios.
• Control Characteristics: Supports optical fiber trigger signal transmission for strong anti‑interference performance in harsh industrial electromagnetic environments. Extremely low gate inductance, connected via coaxial gate feedthrough and multilayer PCB gate drive, avoids gate over‑drive and optimizes drive energy consumption. Good programmability allows parameter adjustment for different power conversion scenarios, providing strong control and data acquisition support for industrial automation and power systems.
