汽车电子在过去30年内经历了几个时代的演变。 从主要采用机械或发动机驱动系统的纯内燃机 (ICE)，到添加电力动力的轻度混合动力 (MHEV)，再到全电池电动汽车 (BEV)应用。 在这三个时代中，用于转换和分配电力的架构甚至基本半导体元件都发生了重大的变化。 本文讨论了这个进化过程和对将来进化的方向做出了一些推测。

With Electronic Power Steering (EPS), the hydraulic system is replaced with an electric motor that aids the driver only when needed. Its digital assistance control can be modified online to adapt to driving conditions. There are, however, several design constraints to consider. One is that the driver does not want to lack the haptic feedback from the tires, especially when a vehicle is large, such as a truck. Other constraints are determined by safety regulations, particularly for automatic guided vehicles. These constraints require adopting an efficient, accurate and redundant system. Gallium nitride technology helps the designers in all these areas.

Power-conversion technologies are experiencing the first tectonic shift since the move from bipolar to MOS. That shift, of course, is due to the viral adoption of wide-bandgap power devices. At this point, GaN is more than a specialty technology; it is a broad-scale replacement for silicon MOSFETs in applications ranging from 30 V up to 650 V — a multibillion-dollar market.

Automotive 48 V/12 V converters are essential in modern hybrid electric vehicles, as the energy is exchanged between the 48 V and 12 V buses. This two-voltage system accommodates legacy 12 V systems and provides higher power for 48V to loads such as vacuum and water pumps, electric super chargers, steering, and audio systems. Among all the requirements for the 48 V/12 V converter, efficiency, power density, size and cost are on the top of the list. This article addresses these design criteria by employing the GaN ePower™ Stage, EPC23101, and compares it with a previous design using discrete EPC2206 devices.

Demonstrating the design of a bi-directional DC-DC converter for automotive 48 V power distribution, showing how GaN technology is a powerful enabler for efficient electrification. The trend towards increasing electrification in the automotive industry enables car makers both to deliver new innovations to market cost-effectively and to meet increasingly stringent emissions legislation. Raising the vehicle’s main bus voltage to 48 V helps meet the demands of power-hungry systems such as the start-stop motor/generator of a mild hybrid vehicle, as well as loads such as electric power steering, electric supercharging, and vacuum and water pumps.

In last month’s Safety & Compliance column in How2Power, “WBG Semiconductors Pose Safety And EMI Challenges In Motor Drive Applications,”[1]Kevin Parmenter made some assertions about the difficulties of using SiC, and to a lesser extent GaN, power semiconductors in large motor-drive applications. This commentary is a response to that article, showing that GaN can be a game changer in low-voltage integrated motors.
