Each of the semiconductor switching elements includes a free wheel diode. The smoothing capacitor is coupled in parallel with a direct current power source and the semiconductor switching elements. The smoothing capacitor smoothes an output of the direct current power source and supplies the smoothed output to the semiconductor switching elements. The snubber circuit is coupled between a first connecting point and a second connecting point in parallel with the semiconductor switching elements. An inductance of a first channel provided from the first connecting point to the second connecting point through the smoothing capacitor is equal to or more than 10 times as large as an inductance of a second channel including the semiconductor switching elements and the snubber circuit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Switching device","description":"A switching device includes a plurality of semiconductor switching elements coupled in series, a smoothing capacitor, and snubber circuit.
