Join gallium nitride (GaN) technology experts in the EPC virtual booth at CES to explore how GaN enables enhanced features and performance in consumer electronics by providing higher efficiency, smaller size, and lower cost semiconductor FET and IC solutions.
EL SEGUNDO, Calif. — January 2021 — Efficient Power Conversion (EPC) announced that it will demonstrate the power of eGaN® technology to boost performance in game-changing consumer applications including self-driving cars, emobility, drones, robots, and 48-volt power conversion at the All-Digital Consumer Electronics Show (CES) January 11th through the 14th.
Gallium nitride (GaN) transistors have been in mass production for over 10 years. In their first few years of availability, the fast switching speed of the new devices – up to 10 times faster than the venerable Si MOSFET – was the main reason for designers to use GaN FETs. As the pricing of GaN devices normalized with the MOSFET, coupled with the expansion of a broad range of devices with different voltage ratings and power handling capabilities, much wider acceptance was realized in mainstream applications such as DC-DC converters for computers, motor drives for robots, and e-mobility bikes and scooters. The experience gained from the early adopters has led the way for later entrants into the GaN world get into production faster. This article is the first in a series of articles discussing three topics that can help power systems designers achieve the most out of their GaN-based designs at the lowest cost. The three topics are: (1) layout considerations; (2) thermal design for maximum power handling; and, (3) EMI reduction techniques for lowest cost.
Bodo’s Power Systems
Brushless DC (BLDC) motors are a popular choice and are finding increasing application in robotics, drones, electric bicycles, and electric scooters. All these applications are particularly sensitive to size, weight, cost, and efficiency. A monolithically integrated GaN power stage is demonstrated powering a 400 W capable BLDC motor with low switching losses and significant savings in size and weight.
