Aiming to jump-start the stalled market for wireless power systems, chip maker Efficient Power Conversion this week announced the launch of a new line of semiconductors made from gallium nitride, a material that’s 10 times faster than silicon and that many believe represents the future of the semiconductor industry. The new chips are designed specifically to support wireless power systems such as those produced by WiTricity.
EPC is headed by chip industry veteran Alex Lidow, who coinvented a type of transistor used for power conversion systems in a range of products including home appliances, air conditioners, and energy-efficient lighting. For many years the CEO of International Rectifier, still the largest producer of such transistors, Lidow has in recent years become one of the leading apostles of using gallium nitride, rather than silicon, to make transistors. EPC’s products are already in use in telecom equipment, satellites, laptop chargers, and virtual-reality devices. Now, says Lidow, his company’s technology is set to overhaul wireless power transfer.
