Air Fuel GaN Power Delivery

Efficient Power Conversion (hall 7-539) offers power systems designers now a 350 V, 65 mΩ, 26 A power transistor in an extremely small chip-scale package. These new EPC2050 devices are ideal for applications such as multi-level converters, EV charging, solar power inverters, and motor drives.

EPC announced also a complete class 4 wireless power kit, the EPC9129. The system can transmit up to 33 W while operating at 6.78 MHz (the lowest ISM band). The kit comes complete with two receivers, each with a regulated output − one capable of 5 W capable and a second capable of delivering 27 W at 19 V. The purpose of this demonstration kit is to simplify the evaluation process of using eGaN FETs for highly efficient wireless power transfer. The EPC9129 utilizes the high frequency switching capability of GaN transistors to facilitate wireless power systems with full power efficiency between 80 and 90 % under various operating conditions. The popularity of highly resonant wireless power transfer is increasing rapidly, particularly for applications targeting large power transmitting surface areas, with the capability to place receiving devices anywhere on the surface, and the ability to simultaneously power (or charge) multiple devices placed on the surface. The end applications are varied and evolving quickly from cell phone charging to powering handheld tablets and laptop computers. Delivering up to 33 W supports all of these applications.
