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.
FPGA based current estimator for pulsed power applications
This paper presents an FPGA implementation of a method intended to minimize the measurement error of the load current in pulsed current applications. The method is based on the inclusion of a sensor model in the system model so as to obtain an extended state-space model enabling to estimate the load current. The implementation of the estimator in an FPGA platform allows to incorporate this block as a stage independent of the converter control. Experimental results validate the implementation of the proposed systems.
Representation of systems disturbed by wide band noise
In this paper, a method of handling and working with wide band noise is developed. We represent wide band noise as a distributed delay of white noise and use it to reduce a nonlinear system disturbed by wide band noise to a nonlinear system disturbed by white noise. An application of this reduction to a nonlinear filtering problem under a wide band noise disturbance is discussed.
