摘要： An electronic ballast which includes a resonant load circuit (L1, C1) in series with a discharge lamp (LA), the resonant load circuit being supplied by an inverter (S1, S2) 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 (7) at variable alternating frequencies above 200 KHZ. Passive components of the ballast and transformer are integrated into a multilayer circuit (13).

摘要： An electronic ballast for controlling the operating behavior and brightness of a gas discharge lamp, includes a full bridge circuit fed with a d.c. voltage (UBUS). The gas discharge lamp is connected as a load of the full bridge circuit, and a control circuit in each case switches on one bridge diagonal and switches off another bridge diagonal of the full bridge circuit, alternatingly. The bridge diagonals each have a regulatable constant current source for regulating a lamp current, and thereby the occurrence of flickering appearances is suppressed. As a result, the lamp can be dimmed over a very wide range of brightnesses.
