A new quasi current resonant dc link (QCRDCL) topology has been developed in this paper. Although prototype current resonant dc link topologies for ac/ac power conversion have had such problems as irregular high current peaks, uncontrollable pulse width, etc., this new topology enables the ac/ac conversion system to have the properties wherein the current peak is limited and the pulse width is adjustable. The system begins to assume an adjustable-width flat-topped current shape, whereby the system becomes particular suitable for high power application. With control of the pulse width a very fine load current regulation can be obtained. In this system, an open loop PWM control has been adopted and almost the same quality of output waveforms as the conventional current source inverter has been achieved.
