| 20080238196 | ENERGY RECYCLE SYSTEM FOR USE WITH AC CURRENT POWER SUPPLY - An energy recycle system for use with an AC current power supply, for example, an electronic ballast, is presented. The energy recycle system includes an energy recycle load connected to an output terminal of the AC current power supply, in which the energy recycle load includes a rectifier for rectifying the output AC current of the AC current power supply into a rectified DC current and a filter connected to the rectifier for removing the high-frequency harmonics from the rectified DC current. Also, the energy recycle system further includes a DC-AC converter connected to the energy recycle load for receiving the DC current outputted from the energy recycle load, which is in turn delivered to the utility grid to achieve energy recycling. | 10-02-2008 |
