Circuit for limiting making current in power supply unit

The invention relates to a circuit for limiting a making current; the circuit can be used in power supply units of operating devices for operating lighting means and comprises at least a first storage capacitor (C1) and a second storage capacitor (C2) which jointly form a voltage source for components to be energized by the power supply unit, the circuit further comprising a switch (S2), by means of which the second storage capacitor (C2) is switched on later than the time the first storage capacitor (D1) begins to be charged. 本发明涉及一种用于限制浪涌电流的电路，该电路可以在用于操作照明设备的操作装置的电源中使用，其中该电路至少包括第一储能电容器(C1)和第二储能电容器(C2)，它们共同构成用于电源供电部件的电压源，该电路还包括开关(S2)，通过该开关，第二储能电容器(C2)相对于第一储能电容器(D1)充电开始而延迟接通。
