System-level approach to NVH models

Complex interactions between electric powertrain components provide significant challenges in accurately predicting the noise, vibration and harshness (NVH) performance of a design when using high level system-level models (writes Nick Flaherty). The models can help reduce the cost and development time, but the underlying interaction of the component-level simulations needs to be understood to achieve […]

Protecting electric ships with rapid DC switching

Potentially critical faults in the high-power DC powertrains increasingly found in ships, particularly ferries, must be isolated as quickly as possible to minimise damage and allow the rest of the system to continue operating as normal (writes Peter Donaldson). Key to this is the application of solid-state power electronics in the form of switches based […]

Design unveiled for 800V inverter from Texas Instruments

Texas Instruments has developed a reference design for an 800 V, 11 kW three-level, three-phase inverter using gallium nitride (writes Nick Flaherty). The inverter uses a 6.6 kW active neutral-point clamped (ANPC) inverter design with a 600 V LMG3422R030 GaN FET. This enables a switching frequency of 100 kHz to reduce the size of the […]

Onboard charger cuts it both ways

Vicor has shown a modular approach for a ‘virtual battery’ that can tackle issues with DC fast charging of EVs (writes Nick Flaherty). Many existing DC fast chargers work with 400 V packs but not the 800V versions. In 2020, there were around 400,000 publicly accessible DC fast chargers around the world, but only 2% […]
