  2. 1. Power Control Systems for PM Synchronous Flywheel Alternators

    Author : Janaína Goncalves de Oliveira; Uppsala universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Flywheel systems are attractive in hybrid and electric vehicles, being able to handle the large power when accelerating and for regenerative braking. The combination of a flywheel device with a battery source has several advantages, such as higher peak power capacity, higher energy density and a decrease of the number of charging/discharging cycles in the battery.
