A new multiple-stage converter topology for high power and high precision fast pulsed current sources

A new high current, low rise time and high precision pulse generator is presented. The topology is based on the use of different stages, each one specific for a particular operation range in terms of power and switching frequency. The design and operating principle of the proposed topology are described. Finally, the results obtained from an implemented reduced scale prototype are compared with the simulation ones in order to validate the design.
