Predictive current control of voltage source inverters

A new current controller for a voltage source inverter based on calculation of an electromotive force is presented in this paper. Practical aspects of realizing the new controller in a system with a signal processor are considered. Delays introduced by measurements are taken into consideration. An improved algorithm with one period prediction of current is presented. Controller was realised in an experimental system with floating point signal processor and with field programmable gate arrays (FPGA). Results of the simulations and experiments are presented
