Power Integrations has developed the SCALE-2 family of IGBT gate drivers, providing a complete solution that integrates galvanic isolation, protection features, and DC/DC power conversion into a single compact module. These advanced gate driver solutions are designed for IGBT modules, power MOSFETs, and emerging wide-bandgap semiconductor technologies such as silicon carbide (SiC) devices operating at switching frequencies up to 500 kHz.
The SCALE-2 IGBT gate driver platform is based on an advanced ASIC chipset that combines the functionality of a dual-channel gate driver core. The architecture includes a primary-side logic-to-driver interface and a secondary-side intelligent gate driver, enabling efficient and reliable control of high-power semiconductor devices.
These gate driver modules are available for applications with blocking voltage ratings ranging from 600V to 6,500V and provide drive power capabilities from 1W to 20W per channel. To optimize switching performance, the modules incorporate separate gate resistors that allow independent control of turn-on and turn-off functions when driving external N-channel DMOS devices.
Single-channel and dual-channel versions are available, providing flexibility for a wide range of power electronics designs. The integrated protection and isolation features help improve system reliability while reducing design complexity and component count.
SCALE-2 gate drivers are widely used in industrial automation, motor control systems, power transmission equipment, railway traction systems, solar inverters, wind energy converters, electric vehicle power electronics, and other high-performance energy conversion applications. As demand for efficient power semiconductor solutions continues to grow, advanced IGBT gate drivers remain essential for improving switching performance, system reliability, and energy efficiency in modern power electronics systems.
