DIMMER CIRCUIT WITH IMPROVED INDUCTIVE LOAD IMBALANCE PROTECTION
Application 1439/KOLNP/2004 published 2006-08-11, filed 2004-09-28
A protection circuit for protecting a dimmer circuit controlling an inductive load including an imbalance detector for detecting an asymetrical operation in the load and circuit control means for causing the dimmer circuit to reduce a DC component in the load upon detection of the asymetrical operation. A load imbalance detector is also disclosed having a load DC component detector, a comparator and a signal generating means for generating means for generating a circuit shut down signal if the DC component exceeds a pre-set DC threshold.
