EEVblog 1737 - Alex Lidow: Inventor of the Power MOSFET

A chat with Alex Lidow, the inventor of the original Power MOSFET and HEXFET at International Rectifier. Former CEO of International Rectifier (founded by his father!), and now Founder & CEO of EPC (Efficient Power Conversion) that make the most efficient GaN FET's on the market. https://epc-co.com We cover everything from inventing the power MOSFET on his first day on the job to silicon physics and AI data centres and humanoid robots. 00:00 - Alex Lidow 05:08 - What's the definition of an Engineer? 06:07 - Inventing the Power MOSFET 400V/1ohm first day on the job with Tom Herman 09:16 - The flash of brilliance: Inject charge into the region 10:36 - Steve Wozniak and the Apple IIE PSU 12:02 - IRF100 and IRF130 HEXFET 14:18 - 42 Competitors! 15:54 - Major Innovations in MOSFET's 17:00 - CoolMOS from Siemens 18:23 - TrenchMOS from Vishay 19:17 - Silicon Carbide started as a diode 21:46 - 2D Electron Gas (2DEG) 24:40 - Silicon MOSFET game is won by the deepest pockets 25:09 - Getting fired from IR and starting Starting EPC 26:28 - Get that damn Gallium out of my Silicon fab! 29:31 - Integrated GaN Solutions 31:03 - The physics of Radiation Hardening in MOSFET's 34:23 - The market for high voltage transistors 36:00 - The 200V and under MOSFET market is performance driven 39:13 - Protecting Patents in China is EASIER than in the US! 41:41 - AI Data centres and NVIDIA modules 44:46 - 800V AI power module architecture 47:42 - Multi level DC-DC topology ISOP 49:46 - Frequency trade-off in LLC DC-DC converter design 56:13 - Humanoid robots 58:16 - What is the most popular GaN? 59:24 - Buyouts? 01:00:36 - Evaluation Boards 01:03:34 - Darkening the digital sky Forum: https://www.eevblog.com/forum/blog/ee...
