Abstract
PURPOSE:To quickly switch a MOS FET by optically insulating the signal input side and a power system from each other by a photoelectric coupling element and performing such correction by a differential waveform generating means that quick rise and fall of a voltage waveform are attained. CONSTITUTION:A part of an input signal IS applied to a signal input terminal 1 is applied to the input of an amplifier A, and a light emitting diode LD on the input side of a photoelectric coupling element IG connected to the output of this amplifier is driven to emit light, and a photoelectric power generating element array PV is excited to generate an electromotive force between both ends, and a voltage waveform PVO is obtained between the gate G and the source S of a MOS FET Q. A part of the input signal IS is led to a differentiating circuit DF to obtain a differential waveform TO, and this waveform is inputted to an amplifier A2. The output of the amplifier A2 generates a voltage having the bipolar differential waveform on the secondary winding side of a coupling transformer T.
