Abstract

To provide an electronic circuit for detecting a peak value of current ringing which occurs when a switching element is turned on.SOLUTION: An electronic circuit comprises: an input terminal; a detection terminal; a diode having a cathode connected to the input terminal and an anode connected to the detection terminal; a resistor part which is connected between the detection terminal and a first reference voltage; and a capacitor which is connected between the detection terminal and a second reference voltage. A voltage equal to the minimum value of a voltage applied to the input terminal is outputted from the detection terminal.SELECTED DRAWING: Figure 4
