Title: Power converter
Inventor: HOSONO YUKIO
IPC: H02M7/48
Filed: 2009-06-26
Abstract: PROBLEM TO BE SOLVED: To provide a power converter detecting an open fault of a transistor, without being affected by a flow-back of current even if it flows back through a diode.SOLUTION: A motor controller is provided with a boosting converter circuit, having a plurality of switching elements, a three-phase inverter circuit and an open fault circuit. The switching element is provided with IGBT, a diode connected in parallel to IGBT and a temperature sensor detecting a temperature of IGBT. An open fault determining means loads the temperature of IGBT, which the temperature sensor detects. When the temperature difference between IGBT is larger than an open fault determining temperature difference, it is determined that IGBT with the lower temperature has an open fault. Consequently, even if a current flows back via the diode, open fault of the transistor can be detected, without being affected by the flow-back of the current.
