I. Basic Information

• Industrial drive systems (e.g., rolling mills, compressors, large motor drives).

• Renewable energy (wind converters, photovoltaic inverters).

• Power systems (HVDC high-voltage direct current transmission, flexible AC transmission systems FACTS).

• Traction systems (rail transit, electric vehicle charging infrastructure).

II. Functions and Applications

• Power Electronic Switch: As a Thyristor module, it controls the on/off of high-current and high-voltage circuits to achieve power conversion and control.

• High-Reliability Switching Device: Supports fast turn-on/turn-off, suitable for high-frequency or pulse applications (e.g., PWM control in inverters).

• Overload and Short-Circuit Protection: Built-in protection mechanisms can withstand short-term overcurrent and overvoltage to ensure system safety.

• Inverters/Converters: Achieves AC-DC-AC conversion in industrial motor drive systems.

• HVDC Converter Stations: Used for rectification and inversion in high-voltage DC transmission systems to enable long-distance and large-capacity power transmission.

• Reactive Power Compensation Devices (SVC/SVG): Regulates reactive power in the power grid to improve power quality.

• Solid-State Circuit Breakers (SSCB): Replaces traditional mechanical switches to achieve arc-free breaking, improving switching speed and service life.

III. Hardware Specifications1. Physical Parameters

• Package Type: Standard power module package (e.g., press-fit or welded ceramic housing for enhanced heat dissipation and electrical insulation).

• Dimensions: Approximately 150mm (length) × 100mm (width) × 50mm (height).

• Weight: Approximately 1.5 kg.

• Mounting Method: Baseplate mounting (requires a heat sink, fixed by screws or welding).

3. Interfaces and Connections

• Main Terminals: 2 anode (A) and cathode (K) terminals for connecting to the main circuit.

• Gate (Trigger Terminal): 1 gate (G) interface supporting low-power trigger signals (e.g., DC voltage pulses).

IV. Technical Characteristics

• High Voltage/Current Capability: Suitable for megawatt-level power electronics systems, supporting high power density designs.

• Fast Switching Performance: Low switching losses, ideal for high-frequency applications (e.g., PWM control in wind converters).

• Redundancy and Parallel Operation: Multiple modules can be paralleled to increase system capacity (requires current sharing measures).

• Thermal Design: Ceramic substrate or metal baseplate enhances heat conduction, requiring efficient heat sinks (e.g., liquid or air cooling).

V. Electrical Properties

• Operating Voltage: DC or AC voltage (dependent on application circuit topology), must match the rated voltage level.

• Power Consumption: Typical on-state loss: IT(AV) × VTM (Example: 3500A × 1.5V = 5.25kW, combined with thermal design).

• Insulation Rating: Complies with standards such as IEC 60664, with insulation withstand voltage meeting high-voltage system requirements.

VI. Application Notes

• Drive Circuit Design: Must match gate trigger voltage and current to avoid mis-triggering or device damage.

• Thermal Management: Ensure the heat sink thermal resistance is sufficiently low to prevent junction temperature from exceeding the rated value.

• Protection Circuits: It is recommended to configure RC snubber circuits or metal-oxide varistors (MOVs) to suppress voltage spikes.

• Parallel Operation: Consider dynamic current sharing (e.g., series inductors) and static current sharing (resistive current sharing) to avoid circulating currents causing device damage.

VII. Product Features

• High Reliability: Industrial-grade design suitable for long-term operation in harsh environments (high temperature, high humidity, vibration).

• High Efficiency: Low on-state voltage drop and switching losses improve system efficiency.

• Flexibility: Supports various topological structures (e.g., three-phase bridges, single-phase bridges) to adapt to different system requirements.

• Long Lifespan: Fatigue-resistant design can withstand millions of switching cycles.
