具有两个独立调节直流输出的三相协同控制电流直流环节AC/DC Buck-Boost变换器

A three-phase current DC-link AC/DC buck–boost converter, composed of a three-phase current-source rectifier (CSR) front-end and a three-level DC/DC-stage, can provide two independently regulated DC outputs. A conventional synergetic control strategy, which coordinates the modulation of the CSR and the DC/DC converter stage to achieve minimum overall switching losses, is extended to the case of tw...
