Abstract :
A full hardware modulator board for space vector modulation which allows for dead time effects compensation is presented in this paper. It consists of a fully integrated digital set-up implemented on a programmable logic device. It is based on an adequate modification of the switching sequence generation on the base of the phase stator current signs and of the power modules status. In this paper, a detailed description of the modulator set-up is provided together with some experimental results
