Infineon KP120: A High-Performance 1200V IGBT for Demanding Power Conversion Applications
The relentless pursuit of higher efficiency, greater power density, and enhanced reliability in power electronics drives continuous innovation in semiconductor technology. At the forefront of this evolution for high-voltage applications is the Infineon KP120, a 1200V IGBT that sets a new benchmark for performance in demanding power conversion systems.
Engineered to excel in challenging environments, the KP120 leverages Infineon's advanced Trenchstop™ IGBT technology. This proprietary cell design is pivotal to the device's outstanding characteristics. It significantly reduces saturation voltage (VCE(sat)) while simultaneously optimizing switching behavior. The result is a remarkable reduction in both conduction and switching losses, which directly translates into higher overall system efficiency and lower operational costs.
A key feature of the KP120 is its soft and robust switching performance. The Trenchstop™ technology, combined with an optimized field stop layer, ensures a smooth turn-off waveform with minimal tail current. This not only reduces electromagnetic interference (EMI), simplifying filter design and compliance, but also minimizes stress on the IGBT itself and its anti-parallel diode, leading to improved long-term reliability. Furthermore, the device offers a wide SOA (Safe Operating Area), providing designers with greater margin and flexibility, especially in applications prone to overload conditions or short-circuit events.
The high voltage rating of 1200V makes the KP120 an ideal choice for a vast array of industrial and renewable energy applications. It is particularly well-suited for:
Industrial Motor Drives: Delivering robust and efficient control for high-power AC motors.
Uninterruptible Power Supplies (UPS): Ensuring high efficiency and reliability in critical power backup systems.
Solar Inverters and Energy Storage Systems (ESS): Maximizing energy harvest and conversion efficiency in renewable installations.
Welding Equipment: Providing the high current handling and durability required for industrial welding.
The module is also designed for ease of use, featuring a low thermal resistance package that enhances heat dissipation and simplifies thermal management design. This allows for either a smaller heatsink or higher output power within the same form factor, pushing the boundaries of power density.
ICGOODFIND: The Infineon KP120 stands out as a superior 1200V IGBT solution, masterfully balancing low losses, robust switching, and high reliability. Its advanced Trenchstop™ technology makes it an exceptional choice for designers aiming to push the limits of efficiency and power density in industrial drives, renewable energy systems, and other high-performance power conversion applications.
