GaN技术杂谈

使用外科手术机器人进行微创手术，为外科医生提供了前所未有的控制力，使其能够实现更高水平的精确度，从而降低患者的风险和创伤并加快恢复速度。许多电机用于控制各种机器人的附肢，如手臂、关节和工具控制，这使得手术机器人具备所需的自由度（DOF）和灵活性，以执行极其精细的操作。因此，电机控制电路的重量和尺寸是这种机器人设计中的重要因素，因为它们直接影响在手术过程中操纵机器人附肢的电机的尺寸。

eGaN® FET能够比Si MOSFET更快地切换，因此需要更加仔细地考虑PCB布局设计，以最大限度地减少寄生电感。寄生电感会导致更高的过冲电压和较慢的切换过渡。本应用说明回顾了设计具有eGaN FET的最佳功率级布局的关键步骤，以避免这些不良影响并最大化转换器性能。

There are many reasons to increase frequency of power conversion.  Fundamentally, these reasons boil down to size/weight reduction, and cost reduction.  There are several components in the design of a power system that must perform efficiently at the targeted increased switching frequencies.  These include power switches, power switch drivers, controllers, magnetics, and capacitors. Taken collectively, these components represent the high frequency power conversion ecosystem.  Without any of these elements, the benefits of increased frequency cannot be fully realized.

Come see the world’s smallest, most efficient, and lowest cost DC-DC converters!  eGaN technology makes this, and much more possible and will be on full display at this year’s American Power Engineering Conference, APEC, where power engineers from around the world gather to see and learn about the latest innovations and products available in the world of power electronics.

EPC GaN experts will be presenting a half-day educational seminar on the state of GaN technology and its application to leading-edge power electronics. In addition, EPC will deliver six technical sessions, as well as demonstrate eGaN applications in our booth and customer suite.

We are quite excited about this year’s CES being held in Las Vegas from January 9th through the 12th.  Our excitement is grounded in the fact that we will be showing the power of GaN technology in two locations – within the AirFuel™ Alliance booth at the Sands Hotel and in our hospitality suite at the Venetian hotel!
