摘要：
AC voltage clipper for a MOS-circuit having two input terminals (In1, In2) receiving an ac supply voltage, wherein one input terminal (In1) is connected to a point of common voltage through a first MOS-transistor (MCL41) and the other input terminal (In2) is connected to said point of common voltage through a second MOS-transistor (MCL42). The gates of MOS-transistors (MCL41, MCL42) are connected to each other and receive a gate voltage (Vg4) of a control circuit (MCL2, MCL3, DCL11,DCL12), in such a way that both transistors (MCL41, MCL42) will conduct when the absolute value of the ac supply voltage, being applied as an input signal to the control circuit (MCL2, MCL3, DCL11, DCL12) exceeds a predetermined threshold value.
