摘要 |
An electronic supply for igniting and operating a high-pressure discharge lamp, comprising a first driven main switching device for generating a high-frequency current through an inductive element and a switching element suitable for subsequently supplying current through the inductive element when the first main switching device is non-conducting. The electronic supply is provided with a transformerless level shifter (LS) and with a driver circuit (S) comprising at least a switch drive device for driving the first driven main switching device. The switching element suitable for the subsequent current supply forms a part of a second driven main switching device which provides periodic commutation of the current through the inductive element, while the level shifter is free from any self-induction elements. |
