Abstract
Methods and apparati for forcing the current through a load (11) in a variable DC electrical circuit to be proportional to the input voltage (V(in)). A circuit embodiment of the present invention comprises a source (27) of input AC; a rectifier (23) coupled to the input AC source (27), said rectifier (23) producing a variable DC input voltage; coupled to the rectifier (23), a load (11) having a variable direct current flowing therethrough; and means (12-16) for forcing the current through the load (11) to be proportional to the variable DC input voltage.
