| 20110128656 | OUTPUT SHORT CIRCUIT PROTECTION FOR ELECTRONIC TRANSFORMERS - An overcurrent protection control circuit for an electronic transformer includes a feedback current detection circuit, an averaging circuit and an overcurrent shutdown circuit. The feedback current detection circuit detects feedback current of an output of the electronic transformer. The averaging circuit determines an average of the feedback current detected by the feedback current detection circuit. The overcurrent shutdown circuit is configured to shutdown the output of the electronic transformer based on the average of the feedback current exceeding a predetermined threshold. The predetermined threshold indicates a short circuit condition. | 06-02-2011 |
| 20080218101 | SOFT START CONTROL CIRCUIT FOR LIGHTING - A low voltage lighting system includes a transformer having at least a primary winding and a secondary winding. The low voltage lighting system also includes one or more lighting elements and a voltage control circuit. The lighting elements are coupled to the secondary winding. The voltage control circuit is electrically coupled with the primary winding. The voltage control circuit is configured to automatically increase the voltage applied to the primary winding of the transformer in a predetermined manner from a first voltage to a second voltage over a predetermined period of time. | 09-11-2008 |
