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 […]

Sigma Powertrain EMAX transmission

Rory Jackson explains how this modular all-electric gearbox can combine two motors to drive any size and weight of EV. High-voltage electric motors produce torque across a wide range of their rpm bands, enabling most electric cars on the road these days to achieve reasonably high power efficiencies with single-speed gear reductions.

Hydrofoiling gives this serial production boat high speed and long endurance. Rory Jackson examines the engineering decisions behind its design. When it comes to designing new kinds of boat hulls that will get as much power and endurance as possible out of battery-electric powertrains, one of the smartest things a maritime architect can do is simply lift the boat out of the water

Lithium-sulphur batteries

Shuttle systems   Lithium-sulphur batteries suffer from short lifetimes from the polysulphide shuttle effect. Nick Flaherty reports on attempts to reduce this The most significant advantage that lithium-sulphur (LiS) batteries offer over rival battery technologies is their substantially higher energy density per unit weight. LiS cells with lithium metal anodes have a theoretical energy density […]
