DEVELOPMENT OF DISTRIBUTED-TYPE LINEAR GENERATOR WITH DAMPING CONTROL

The superconducting Maglev system suspended by EDS (electrodynamic suspension) intrinsically has negative magnetic damping. In order to improve the magnetic damping, a linear generator was used by controlling the power factor of the current in the linear generator coils. A PWM converter and a simulator (using Micro Cap VI) were developed for this control. The article describes how to control the PWM converter and subsequently the power factor and the result of confirmation of this control method through simulation and synthetic bench tests.
