Abstract
The invention relates to a monitoring circuit (ÜS) for a switched-mode power supply with a rectifier circuit (G) for rectifying a primary mains alternating current (AC). The monitoring circuit (ÜS) comprises two resistance dividers (W1, W2) each comprising two resistors (R1, R2, R3, R4). The resistors (R1, R2, R2, R4) are each connected in series between a phase conductor (PH1, PH2) of a mains connection before the rectifier circuit (G) and a reference point after the rectifier circuit (G). The monitoring circuit further comprises a subtraction device (OP) with two inputs, wherein each of the two inputs of the subtraction device (OP) is connected between the resistors (R1, R2, R3, R4) of one of the resistance dividers (W1, W2) in each case. The invention further relates to the use of a monitoring circuit.
