  • BIDIRECTIONAL RESONANT DIRECT CURRENT-DIRECT CURRENT CONVERSION CIRCUIT AND UNINTERRUPTIBLE POWER SUPPLY
    Publication number: 20190334444
    Abstract: A bidirectional resonant current-direct current conversion circuit and an uninterruptible power supply are provided. The bidirectional resonant current-direct current conversion circuit includes a full-bridge conversion module, a transformer, and a half-bridge conversion module. The full-bridge conversion module is coupled to the half-bridge conversion module via the transformer. The full-bridge conversion module is configured to convert two-level direct current power into alternating current power, and the half-bridge conversion module is configured to convert the alternating current power outputted by the full-bridge conversion module into three-level direct current power. The half-bridge conversion module is further configured to convert three-level direct current power into alternating current power, and the full-bridge conversion module is further configured to convert the alternating current power outputted by the half-bridge conversion module into two-level direct current power.
