Title:

POWER CONVERSION DEVICE

Document Type and Number:

WIPO Patent Application WO/2010/150549

Kind Code:

A1

Abstract:

Disclosed is a power conversion device which achieves reductions in switching loss due to a reverse recovery current and heat generation loss. Specifically disclosed is a power conversion device provided with a cascode element (21) configured by electrically connecting a normally-on switching element (4) and a normally-off switching element (5) in series and connecting a gate terminal of the normally-on switching element (4) and a source terminal of the normally-off switching element (5) via a cascode connection diode (7), and a high-speed diode (6) electrically connected in parallel with the cascode element (21) and having a cathode region connected to a positive electrode terminal and an anode region connected to a negative electrode terminal.
