摘要： A free-running inverter for a load, especially a low-voltage lamp, with a series circuit of two controllable switches (10, 11) which interconnects both inputs of the inverter connected to a rectified a.c. voltage, a control voltage having to exceed a given threshold to operate the switches (10, 11); and a trigger component (21) connected to one of the two control inputs of the switches (10, 11), the trigger component (21) having a voltage swing which is greater than the threshold voltage of the switches (10, 11), and the voltage excursion giving the voltage range between the breakdown voltage and the level to which the voltage returns after the breakdown.

摘要： In a free-running inverter for a load, especially a low-voltage lamp, with a bridge rectifier circuit (2-5) which provides a rectified a.c. voltage to two output terminals (a1, a2), a series circuit comprising two controllable switches (10, 11) which connects the two output terminals (a1, a2) of the rectifier circuit, a series circuit comprising two capacitors (12; 13) arranged in parallel with the switches (10, 11), and a protective citcuit (F) which is connected to a current measuring instrument (E) for the load current and switches the inverter off at too high a load current, there is a voltage divider circuit (23-26) between the two input terminals of the rectifier circuit (2-5), and the supply voltage for the protective circuit (F) is taken between the central tapping of the voltage divider circuit (23-26) and an output terminal (a2) of the rectifier circuit (2-5).
