In this video from APEC, Marco Palma, Director, Motor Drives Systems and Applications at EPC, presents advanced motor drive reference designs based on gallium nitride (GaN) technology. He first highlights the EPC91122 reference design, featuring the EPC33110 three-phase power module used to drive a mid-size drone motor and a high-torque humanoid robot joint. He then introduces the EPC91121, a highly integrated board for power tools, built on EPC’s latest Gen 7, 40 V GaN devices. Both platforms showcase compact form factor, high efficiency, and easy scalability from 250 W up to 5 kW for rapid prototyping.

In this video, you will find a conversation with Alex Lidow - the inventor of the original Power MOSFET and HEXFET during his time at International Rectifier. Alex later became CEO of the company founded by his father and today is the Founder and CEO of Efficient Power Conversion (EPC), known for producing some of the most efficient GaN FETs on the market. In the discussion, you will hear the story of how the power MOSFET was invented - on Alex’s very first day on the job - and how that breakthrough helped shape modern power electronics.

The conversation also dives into silicon physics, the rise of GaN technologies, and the growing power demands of AI data centers and humanoid robots, offering a fascinating perspective that connects the origins of power semiconductors with the technologies driving the future of computing and electrification.
