Inventing the Power MOSFET with Alex Lidow
Alex Lidow, founder and CEO of Efficient Power Conversion (EPC) and former CEO of International Rectifier, recounts inventing the Power MOSFET and HEXFET while working at IR. He explains the physics of Gallium Nitride (GaN) on silicon, the founding of EPC after being fired from IR, and the company's strategic focus on low-voltage performance markets and integrated circuits for AI data centers and humanoid robots. Lidow also discusses the challenges of patent enforcement in the US versus China and the technical details of high-efficiency power topologies for next-generation NVIDIA servers.
