Vivarail battery electric train. Vivarail have produced the Class 230 train which is converted from redundant London Underground D-Stock trains. A demonstrator unit, the two-car 230002, was fitted for diesel-electric- battery power. Vivarail developed a fast charger giving a 100 mi (160 km) range with a 10 minutes recharging time. [1]
IUoU is a DIN-designation [1] (DIN 41773) for a lead-acid battery charging procedure that is also known as 3-stage charging, 3-phase charging, or 3-step charging. It consists of three phases (or stages), to be executed by a battery charger. The three phases are: I-phase (constant electric current), Uo-phase (constant over-voltage), and U-phase ...

A three-phase induction motor has a simple design, inherently high starting torque and high efficiency. Such motors are applied in industry for many applications. A three-phase motor is more compact and less costly than a single-phase motor of the same voltage class and rating, and single-phase AC motors above 10 hp (7.5 kW) are uncommon. Three ...
Public EV charging stations often provide 6 kW (host power of 208 to 240 V AC off a 40-ampere circuit). 6 kW will recharge an EV roughly six times faster than 1 kW overnight charging. Rapid charging results in even faster recharge times and is limited only by available AC power, battery type, and the type of charging system. [21]
The 3.2-litre, five-cylinder diesel engines are manufactured by Ford in South Africa. [16] Lithium Werks (formerly Valance) is the supplier of the battery rafts, while the electronic power control systems are produced by Strukton Rail. The three-phase AC traction motors are sourced from specialist Traktionssysteme Austria. Reportedly, the ...
An American Rotary Phase Converter with a Transformer. A phase converter is a device that converts electric power provided as single phase to multiple phase or vice versa. The majority of phase converters are used to produce three-phase electric power from a single-phase source, thus allowing the operation of three-phase equipment at a site that only has single-phase electrical service.
A soft-switching three-level inverter (S3L inverter) is a high-efficiency power electronic inverter intended, in particular, for use with three-phase drives, as a grid-tie inverter for photovoltaic installations or wind turbines and in power supplies. [1] The topology was developed in 2009 at HTWG Konstanz (Constance University of Applied ...
