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.
