Analysis and design of a higher-order T-type resonant convertor as a constant-current power supply

open access: yesIET Power Electronics, 2011
A higher-order resonant convertor (RC), named LCLCL-T RC, is proposed in this study. It is shown that the convertor behaves as a constant-current (CC) source under certain operating conditions. The proposed convertor additionally offers inherent dc blocking for the isolation transformer and integration of all magnetic components reducing the number of ...
