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 【課題】スイッチング素子のターンオン時に発生する電流リンギングのピーク値を検出する電子回路を提供する。【解決手段】本実施の形態の電子回路は、入力端子と、検出端子と、入力端子にカソードが接続される共に、検出端子にアノードが接続されるダイオードと、検出端子と第１の基準電圧との間に接続される抵抗部と、検出端子と第２の基準電圧との間に接続されるキャパシタとを備える。検出端子からは、入力端子に印加される電圧の最小値と等しい電圧が出力される。【選択図】図４
