ABSTRACT:
A fluorescent lamp controller uses a dimmer circuit having an isolation transformer. The controller applies a high frequency current to the primary winding of the transformer. The secondary winding is coupled to a control input via loading circuitry. A detector circuit supplies a signal to the lamp controller indicative of the resultant loading of the transformer to control lamp intensity.
