Sponsored by HBK Extended monitoring of electrical power needs to be done for power grids and inverter-driven electric machines to characterize their long-term behavior. This is often quite difficult to do and can contain data that is overwhelming and hard to understand. This whitepaper will showcase a real-life example of a monitoring test done over… Read more »
The battery life of a device is crucial for the adoption of more electric devices. One of the main drivers for improving battery life is minimizing losses in the power conversion. Power losses happen for a variety of reasons in both the motor and inverter. In this presentation, we will review the basic sources of losses in… Read more »
Sponsored by HBK In recent years there has been an increased interest in electric and more electric aircraft, including both novel all-electric aircraft, drones, rigid air ships and traditional aircraft with efficient and more electric components. Validating these systems and components has challenges due to the nature of aerospace testing as well as the high… Read more »
Sponsored by HBK In an electric powertrain the motor, inverter, and gear box need to work together to give the desired performance and experience for the end user. Ideally, these components should be designed to work together, but that is rarely the case, as the parts come from a variety of suppliers. All the components… Read more »
Sponsored by HBK Understanding how vehicles use and distribute energy is crucial for electric vehicle development and certification. Electrical powertrain, including motors and inverters, heating, air conditioning, infotainment, and other sub systems all consume energy that is being supplied by the battery pack. Any energy usage or inefficiency can result in a shorter range of… Read more »
