Abstract :
A simplified parallel resonant DC link (PRDCL) inverter topology with reduced peak voltage is presented. A novel current prediction scheme which facilitates interfacing the resonant link topology to an AC motor is proposed. Various simulation waveforms and experimental results are given to show the effectiveness of the proposed current prediction scheme. Some studies relating to the selection of resonant component values and the characteristic impedance of the link on the voltage overshoot are presented. This study makes it possible to design drives without clamping
