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.

基於氮化鎵元件的EPC9167 逆变器参考設計提高馬達系统性能、範圍、精度、扭矩並同時降低整體系统成本。該逆變器尺寸超小，可整合到電機外殼中，從而實現具有最低 EMI、最高功率密度和最輕的馬達驅動逆變器。

宜普電源轉換公司（EPC）宣佈推出 EPC9167，這是一款採用 EPC2065 eGaN^® FET的三相 BLDC馬達驅動逆變器。EPC9167在14 V和60 V（標稱48 V）之間的輸入電壓下工作，並備有两種配置——標準和大電流版本：

A few simple thermal management guidelines can help conduct heat away from GaN FETs. Enhancement-mode gallium nitride (eGaN) FETs offer high power-density with ultra-fast switching and low on-resistance, all in a compact form factor. However, the power levels these high-performance devices provide can be limited by extreme heat-flux densities. If not managed properly, the generated heat can compromise reliability and performance. Fortunately, chip-scale packaging for eGaN FETs can be leveraged at the board-side and the backside (i.e., case) to better dissipate heat.

Efficient Power Conversion (EPC) publishes Phase-14 Reliability Report, which adds to the extensive knowledge and demonstrates a robustness capability unmatched by silicon power devices.

EL SEGUNDO, Calif.— February 2022 — EPC announces its Phase-14 Reliability Report, documenting the strategy used to achieve a remarkable field reliability record. The rapid adoption of GaN devices in many diverse applications calls for the continued accumulation of reliability statistics and research into the fundamental physics of failure in GaN devices. The Phase-14 Reliability Report presents the strategy used to measure and predict lifetime based upon tests that force devices to fail under various conditions. This information can be used to create more robust and and higher performance products for applications such as lidar for autonomous cars, robotics, security, and drones, high power density computing, and satellites, to name just a few.
