Benefits of our GaN IPMs
Increase system efficiency
Our intelligent power modules integrate low on-resistance high-voltage GaN devices that enable inverter efficiency gains of 2% and reduce power losses 50% or more over IGBT or MOSFET modules.
Extend motor-drive lifetimes
Integrated slew-rate control and multilevel protection help reduce motor heating, maximize power efficiency and enhance insulation over a motor's lifetime.
Enable quiet and accurate motor operation
Achieve accurate current sensing with low propagation delay and reduce current harmonics with low dead time. Low duty-cycle support enables a wider operating range of motor speeds.
Improve power density and reduce system costs
Reduce system size as much as 60% by eliminating the heat sink and integrating a current-sensing amplifier and protection features.
