<p>The arrangement has an igniter (Z1) coupled between a connection point of an ohmic resistor (R1) and a capacitor (C1) on one side and a control electrode of an electronic switch (T2) on another side. A microprocessor (10) has inputs (E3, E4) and outputs (A3, A4), where one of the inputs (E3) is connected with a decoupling point between an output of diodes (D1-D4) and outputs (A1, A2). The decoupling point is formed such that the amount of potential of the point falls below a preset threshold value if an intermediate circuit voltage (Uz) falls below another preset threshold value.</p> |
