Abstract
In a module using a high-speed switching element such as an IGBT for a high-speed inverter, a matching condition is established between the switching characteristic of the IGBT and the recovery characteristic of the diode to be connected thereto in an anti-parallel fashion. As a result, the oscillating voltage appearing in the inverter circuit is suppressed to prevent erroneous operation of the inverter system.
