PP100B120

Overview

The Powerex PP100B120 is a POW-R-PAK™ H-Bridge IGBT assembly rated for 100A continuous collector current and 1200V blocking voltage. It integrates F-series trench gate IGBTs with low conduction and switching losses, mounted on a forced air-cooled heatsink. The unit includes a DC-link capacitor bank of 3300 µF, optically isolated gate drive interfaces, and isolated power supplies. It supports DC bus voltages up to 800VDC and switching frequencies above 20kHz.

Feature Summary

• Integrated gate drive board featuring fault monitoring and protection against overvoltage, undervoltage lockout, overcurrent, overtemperature, and short circuits.
• Low inductance laminated bus structure designed to minimize switching voltage spikes and improve electromagnetic compatibility.
• Built-in analog feedback signals for output current measurement, DC link voltage monitoring, and heatsink temperature sensing.
• System status and troubleshooting LEDs provide visual verification of operational states and error conditions.

Applications

• Motor control systems
• Power supply converters
• Uninterruptible power supplies (UPS)
• Industrial choppers

Procurement Notes

Verify the specific datasheet revision and part number suffix when ordering, as configurations may vary. Confirm that the required mating connectors, specifically the 26-pin IDC socket and strain relief, are included or sourced separately. Ensure the cooling system provides the specified 1500 LFM airflow to maintain thermal limits. Check for any regional compliance certifications required for the target market.

Selection Notes

Select this assembly for applications requiring an integrated H-bridge solution with built-in protection and feedback. It is suitable for designs needing high efficiency through low-loss IGBT technology. Consider the weight and mounting torque requirements for the mechanical design. Verify that the control interface matches the PWM signal thresholds and isolation requirements of the system controller.

Part Context

This component belongs to the Powerex POW-R-PAK™ family of configurable IGBT-based power assemblies. These modules are designed to simplify power conversion system design by integrating the power stage, gate drive, and protection circuitry into a single unit. The series offers various current and voltage ratings to accommodate different power levels and application topologies.

Replacement Considerations

Direct replacements must match the 100A/1200V rating and H-bridge topology. Verify pin compatibility for the 26-pin gate drive interface. Check if alternative modules include similar integrated features like DC-link capacitors and feedback signals to avoid redesigning the control board.
