Abstract
An electronic ballast which includes a resonant load circuit (L, C) in series with a discharge lamp (LA), the resonant load circuit being supplied by an inverter (S, S) which outputs variable alternating voltages at frequencies above 200 KHZ. Alternatively, an electronic transformer incorporates a load circuit and a variable output frequency inverter for operating a low volt halogen lamp () at variable alternating frequencies above 200 KHZ. Passive components of the ballast and transformer are integrated into a multilayer circuit ().
