To provide an electronic circuit and a power converter capable of generating a waveform for driving a semiconductor element with ease.SOLUTION: An electronic circuit comprises: a control circuit that controls a drive circuit of a semiconductor element; and a delay circuit. On receipt of a first signal that designates drive of the semiconductor element at a first driving force, the delay circuit outputs the first signal to the control circuit. On receipt of a second signal designating drive of the semiconductor element at a second driving force at an interval of a first time or an interval n times as long as the first time (n is an integer of 2 or more) after receiving the first signal, the delay circuit delays the second signal by a delay amount shorter than the first time, and after the first time or the time n times as long as the first time and the delay amount have elapsed from outputting of the first signal, the delay circuit outputs the second signal to the control circuit.SELECTED DRAWING: Figure 1 【課題】半導体素子を駆動する波形を容易に生成可能にする電子回路及び電力変換器を提供する。【解決手段】本実施形態に係る電子回路は、半導体素子の駆動回路を制御する制御回路と、前記半導体素子を第１駆動力で駆動することを指示する第１信号を受けて前記第１信号を前記制御回路に出力し、前記第１信号を受けた後、第１時間の間隔もしくは前記第１時間のｎ倍の時間の間隔（ｎは２以上の整数）で、前記半導体素子を第２駆動力で駆動することを指示する第２信号を受けて、前記第２信号を前記第１時間より短い遅延量だけ遅延させ、前記第１信号の出力から前記第１時間もしくは前記第１時間のｎ倍の時間と前記遅延量とが経過した後、前記第２信号を前記制御回路に出力する遅延回路と、を備える。【選択図】図１
