Flying capacitor circuit, circuit module and power conversion apparatus

If current path is switched via switching, voltage overshoot exceeding the device breakdown voltage may be generated. A flying capacitor circuit is provided, having a plurality of switching devices cascade-connected on a first surface of a substrate; a plurality of rectifier devices cascade-connecte...

Beschreibung
Zusammenfassung:	If current path is switched via switching, voltage overshoot exceeding the device breakdown voltage may be generated. A flying capacitor circuit is provided, having a plurality of switching devices cascade-connected on a first surface of a substrate; a plurality of rectifier devices cascade-connected on a second surface of the substrate; and at least one capacitor provided in a wiring connecting main terminals of a switching device and a rectifier device that are associated with each other and included in the plurality of switching devices and the plurality of rectifier devices; and at least part of the wiring runs sandwiching the substrate in parallel.
