Introduction to GaN IPMs
Intelligent power modules (IPMs) built with gallium nitride (GaN) enable higher power density and efficiency than 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, reduce current distortion to improve acoustic performance.
