Pulsed power system with local energy storage for optimizing the power taken from the electrical network

This work presents a topology for a pulsed current power supply suitable for particle accelerator applications. The current pulse is generated from the energy provided by a structure tied to the electrical network and by one connected to a capacitor bank; which is used as local energy storage. By using both structures, disturbances on the electrical network are minimized, since the power obtained from the grid is limited to the average active power of the load; while the management of the reactive power lies on the energy storage structure. A control scheme for the power management of both structures is presented, and simulations are carried out taking into account the parameters of a particle accelerator transfer line.
