How to Integrate GaN Power Stages for Efficient Battery-Powered BLDC Motor Propulsion Systems

How to Integrate GaN Power Stages for Efficient Battery-Powered BLDC Motor Propulsion Systems

This article discusses the advantages of GaN-based power stages and introduces a sample device from EPC, implemented in a half-bridge topology. It explains how to use associated development kits to quickly get started on a project. In the process, designers will learn how to measure the parameters of a BLDC motor and operate it in sensorless field orientation control (FOC) with minimal programming effort using Microchip Technology’s motorBench Development Suite.

High Performance 1 kW per Phase 48 V/12 V Converter Using GaN ePower Stage

High Performance 1 kW per Phase 48 V/12 V Converter Using GaN ePower Stage

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.

氮化鎵元件緩解了矽元件的問題

氮化鎵元件緩解了矽元件的問題

就像生活要面對現實一樣,老年人離開舞臺而讓位給年輕人,矽元件也是需要向現實低頭。 隨著氮化鎵元件的問世和普及,正逐步淘汰舊有可靠的矽元件。 在過去的四十年中,隨著功率MOSFET元件的結構、技術和電路拓撲的創新與不斷增長的電力需求同步發展,電源管理的效率和成本一直以來得以穩步改善。 但是,在業界發展的新時代,隨著矽功率MOSFET元件接近其理論極限,其演進速度下降了很多。 同時,新材料氮化鎵的理論性能極限穩步發展,其性能極限比老化的MOSFET元件高出6,000倍,並且比目前市場上最好的氮化鎵產品高出300倍。
