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% […]

Holding electronics together under high voltages and temperatures

While EVs may have much in common with consumer electronics, the combination of high voltages and powers, and the safety-critical nature of many of their systems, is providing some major headaches for printed circuit board assembly (PCBA) contractors and electronics manufacturing services (EMS) providers – headaches that vehicle OEMs won’t be able to cure with […]
