Gallium nitride (GaN) intelligent power modules (IPMs)

Maximize power efficiency in high-voltage motor-drive applications with our integrated gallium nitride (GaN) intelligent power modules (IPMs)

parametric-filterView all products
Our integrated GaN IPMs achieve greater than 99% inverter efficiency, removing the need for an external heat sink and improving thermal performance with reduced power loss. Advanced integration and higher power density enable reduced solution size and system-level costs. Ultra-low dead time and propagation delay improve acoustic performance with reduced current harmonics and higher-accuracy current sensing. Maximized power efficiency, zero reverse recovery, accurate slew-rate control, and short-circuit and overcurrent protection improve system reliability and extend motor-drive lifetimes.

Introduction to GaN IPMs

Intelligent power modules (IPMs) built with gallium nitride (GaN) enable higher power density and efficiency compared with traditional silicon metal-oxide semiconductor field-effect transistors and insulated gate bipolar transistors. 

Benefits:

  • >99% efficiency in the power stage eliminates the need for cooling components such as heat sinks, improving overall efficiency and reducing motor-driver system size.
  • <150ns dead time and propagation delay, along with higher pulse-width modulation switching frequencies, reduces current distortion to improve acoustic performance.
