Abstract

Described is an electronic transformer designed to operate a low-voltage halogen lamp (1), the transformer having a harmonics filter (R1, R2, L1, C1, C2), an inverter with two switches (2, 3) controlled to switch on and off alternately, a control circuit designed to switch the two switches (2, 3) on and off, and a transformer (16) which delivers the voltage produced at the inverter output to the lamp (1). The control circuit dims the lamp (1) by changing the cycle ratio between the switched-on time for the first switch (2) and the switched-on time for the second switch (3) in the inverter. When the lamp is operating undimmed, the switched-on times are identical for both switches (2, 3).
