Summary: | To provide a high-capacity power conversion device of which the cost of manufacture is suppressed.SOLUTION: A power conversion device comprises a plurality of switching elements. Each of the switching elements includes a leg including an upper arm and a lower arm, and at least either upper arms or the lower arms are connected in series. Each of the plurality of switching elements includes a control terminal, a first end and a second end. The power conversion device comprises a first circuit including a first resistor which is electrically connected between the control terminal and the first end of each of the plurality of switching elements, and a first capacitor which is connected in parallel with the first resistor.SELECTED DRAWING: Figure 2
【課題】 製造コストを抑えた大容量の電力変換装置を提供する。【解決手段】 実施形態によれば、電力変換装置は、上アームと下アームとを含むレグを備え、上アームと下アームとの少なくとも一方が、直列に接続された複数のスイッチング素子を備える。複数のスイッチング素子の各々は、制御端子と、第1端と、第2端と、を備える。電力変換装置は、複数のスイッチング素子の各々の制御端子と第1端との間に電気的に接続された第1抵抗器と、第1抵抗器と並列に接続された第1コンデンサと、を含む、第1回路を備える。【選択図】図2 |
