SINGLE-PHASE CYCLOCONVERTER WITH INTEGRATED LINE-CYCLE ENERGY STORAGE |
| 摘要 |
A method and apparatus for line-cycle storage of a single-phase cycloconverter. The method includes receiving input power from an input port of the singe-phase cycloconverter and monitoring an AC output port of the single-phase cycloconverter. The method measures energy stored in a line-cycle energy storage circuit coupled to one line of the AC output port of the single-phase cycloconverter, and determines a phase difference between a monitored AC voltage of the AC output port and the measured voltage of the line-cycle energy storage circuit. The method controls switches in the single-phase cycloconverter to selectively store energy in the line-cycle energy storage circuit based on the phase difference. |

1. A method for line-cycle energy storage in a single-phase cycloconverter comprising:
receiving input power from an input port of the singe-phase cycloconverter; monitoring an AC output port of the single-phase cycloconverter; measuring energy stored in a line-cycle energy storage circuit coupled to one line of the AC output port of the single-phase cycloconverter; determining a phase difference between a monitored AC voltage of the AC output port and the measured voltage of the line-cycle energy storage circuit; and controlling switches in the single-phase cycloconverter to selectively store energy in the line-cycle energy storage circuit based on the phase difference. |
