摘要： The invention relates to a circuit arrangement for operating electrical lamps which encompasses an invertor (WR) with oscillation build-up circuit (trigger generator), comprising diac (DC1) and drive circuit. The drive circuit comprises a high-pass filter, in particular an RC high-pass filter (R1, C1). As a result, the trigger initiation is shifted closer to the zero crossing of the supply voltage. This means, in turn, that a more sinusoidal power supply current consumption with a smaller proportion of harmonics is obtained. In addition, more stable lamp operation is achieved in combination with power supply segment control dimmers.

摘要： A radio frequency (RF) power supply for an electrodeless lamp includes a pair of DC rails, an RF inverter having power input terminals connected between the rails, a first inductor arranged to inductively couple with an electrodeless lamp, first and second resonance capacitors that each connects a respective one of two input terminals of the first inductor to a same first rail of the pair of DC rails, and a second (ballasting) inductor connecting an output of the RF inverter to one of the two input terminals of the first inductor. Thus, the first inductor is connected in a symmetrical π-filter and supplied by two equal but phase-opposite voltages whose sum is the lamp voltage. The inductance of the ballasting inductor is significantly reduced so that the RF efficiency of the power supply is 96%.
