GE THFP-363L

Product Overview

Product Parameters

• Product Model: THFP-363L
• Manufacturer: GE Industrial Solutions (formerly Toshiba-Hitachi)
• Product Type: Medium-voltage inverter power unit
• Rated Voltage: 690V AC (up to 3.3kV/6.6kV after unit cascading)
• Rated Current: 363A (continuous) / 544A (1-minute overload)
• Switching Device: 1700V IGBT (PWM frequency adjustable from 0.5-2kHz)
• Efficiency: >98% (at full load)
• Cooling Method: Forced air cooling (with built-in dual-fan redundancy)
• Protection Functions: Overcurrent, overvoltage, overheating, short circuit (microsecond-level protection)
• Communication Interface: Optical fiber interface (communication with main control board)
• Operating Temperature: 0°C ~ +40°C (derated to 50°C)
• Protection Class: IP20 (must be installed in the inverter cabinet)
• Weight: 35kg

Structure and Composition

Power Conversion Layer:

• H-bridge circuit composed of IGBT modules (Mitsubishi/Infineon 1700V series).
• DC bus capacitors (film capacitors with low ESR design).

Control and Drive Layer:

• DSP controller for PWM signal generation and fault protection.
• Fiber optic receiver for isolating high and low voltage signal transmission.

Heat Dissipation and Mechanical Layer:

• Aluminum heat sink + redundant centrifugal fans (supporting N+1 backup).
• Slide rail mounting structure with mechanical interlock (for operational safety).

Main Features and Advantages

High Energy Efficiency:

• The multi-level topology results in output voltage harmonics <3%, reducing motor loss by 20%.
• Automatic sleep function (standby power consumption <100W when no-load).

High Reliability:

• Dual design of the IGBT drive circuit to avoid false triggering.
• Capacitor life prediction algorithm (monitored via Proficy CSense software).

Intelligent Maintenance:

• Front LCD panel displays real-time data of voltage/current/temperature.
• Supports hot-swap replacement (requires system derating operation).

System Compatibility:

• Can replace the old THFP-362L module (requires firmware upgrade).
• Seamless integration with the GE MV3000 inverter cabinet.

Application Fields

Water Industry:

• Speed regulation of large water pumps (cooperating with GE AF-650 inverter).

Petrochemical Industry:

• Compressor anti-surge control (PID regulation accuracy ±0.1%).

Power Industry:

• Frequency conversion drive for boiler induced draft fans (replacing fluid coupling speed regulation).

Related Products

• THFP-363L-SP: Standby power unit (with pre-installed firmware).
• THIO-100: Inverter main control board, managing unit cascading.
• THPS-500: System power module, supplying power to the control circuit.
• GE MV3000: Complete cabinet solution (including 6/12 units).
• Proficy CSense: Predictive maintenance software, analyzing capacitor aging.

Installation and Maintenance

Pre-installation Preparation:

• Confirm that the slide rails in the cabinet are aligned, and the unit number is consistent with the system configuration.
• Use an insulation tester to check the IGBT module (the resistance between terminals should be >1MΩ).

Maintenance Recommendations:

• Clean the air duct filter every 6 months (washable PET material).
• Measure the capacitor capacitance annually (replace if attenuation >15%).
• Run automatic voltage balance calibration after replacing the unit.
