PK110FG160 | Robust 1600V PIM IGBT for High-Voltage Industrial Drives
The PK110FG160 is a high-performance Power Integrated Module (PIM) engineered for reliability in demanding, high-voltage power conversion systems. By integrating a three-phase inverter bridge, a brake chopper, and an NTC thermistor into a single, robust package, this module provides a streamlined solution for engineers developing compact and efficient motor control and power supply applications.
- High Voltage Rating: With a 1600V collector-emitter voltage (Vces), it offers a substantial safety margin for systems operating on 690V AC industrial mains.
- Integrated PIM Design: Combines a 7-pack configuration (six IGBTs for the inverter and one for the brake circuit) to simplify system layout, reduce component count, and minimize stray inductance.
- Optimized for Motor Control: Rated for 75A continuous current (at Tc=80°C), making it ideal for controlling AC industrial motors in the 30-45 kW power class.
- Built-in Thermal Sensing: Includes an NTC thermistor for real-time temperature monitoring, enabling critical thermal protection and enhancing overall system longevity.
Application Scenarios: Where the PK110FG160 Excels
The standout feature of the PK110FG160 is its 1600V rating, which makes it a prime candidate for power electronics operating in harsh electrical environments. While standard 1200V modules are sufficient for 400/480V systems, they lack the necessary voltage headroom for higher industrial standards.
- Heavy-Duty Variable Frequency Drives (VFDs): In industrial plants, mining operations, and large-scale HVAC systems that utilize a 690V AC grid, this module provides the required voltage blocking capability to withstand transient overvoltages, ensuring reliable motor operation. The integrated brake chopper is essential for managing regenerative energy during motor deceleration, a common scenario in hoist and conveyor applications.
- High-Power Servo Drives: For large robotic arms and industrial automation machinery requiring precise motion control at higher power levels, the PK110FG160 delivers the necessary current and voltage. Its PIM architecture contributes to a more compact drive design, a critical factor in space-constrained machine cabinets. Explore the critical role of IGBTs in robotic servo drives for more context.
- Industrial Power Converters & UPS: In applications like high-power Uninterruptible Power Supplies (UPS) and specialized power converters, the module's robust design and high voltage rating ensure continuous, reliable power delivery even under fluctuating grid conditions.
Technical Deep Dive: The Engineering Trade-offs
Selecting the right IGBT module involves understanding the trade-offs between key parameters. The PK110FG160 is a testament to a design philosophy prioritizing ruggedness and high-voltage capability. Its VCE(sat) of 2.70V (max) is a direct consequence of the thicker drift region required for a 1600V blocking voltage. While this results in slightly higher conduction losses compared to lower-voltage alternatives, it is a necessary compromise for achieving superior ruggedness and a wider Safe Operating Area (SOA) in high-voltage designs. For engineers, this means effective thermal management is key, a task simplified by the module's integrated NTC thermistor and low thermal resistance package. Understanding this balance is key, as covered in our guide to IGBT selection beyond VCE(sat).

Engineer's FAQ
Here are answers to common questions our engineering team receives about this type of module.
- Why not just use a standard 1200V module for a 690V system?
While a 690V AC RMS voltage translates to a peak line-to-line voltage of around 975V, this doesn't account for transient overvoltages from motor inductance, cable ringing, or grid instability. A 1200V module provides very little safety margin, risking catastrophic failure from overvoltage breakdown. The 1600V rating of the PK110FG160 provides the robust headroom required by industry best practices for reliable, long-term operation. Understanding these failure modes is crucial; learn more about preventing IGBT failure.
- What is the primary benefit of the integrated brake chopper?
The integrated brake chopper simplifies the overall drive design significantly. Instead of specifying, sourcing, and mounting a separate IGBT and diode for the braking circuit, it's already included and thermally managed within the same Power Integrated Module (PIM). This reduces assembly time, lowers component count, and minimizes parasitic inductance between the inverter and brake stages, leading to a more reliable and compact system.
