ELECTRICAL POWER CONVERTER

摘要

The present specification relates to an electrical power converter including two serially connected transistors, and provides a technique for suppressing any increase in electrical current flowing through both transistors when the transistors are on due to a fault of some kind. This electrical power converter includes a first transistor (6a) and second transistor (6b) connected in series. The electrical power converter is provided with a clamp circuit (5) for suppressing an abnormal rise in the gate voltage in the first transistor (6a) and/or the second transistor (6b). The clamp circuit (5) includes a diode (14) and a capacitor (15). An anode of the diode (14) is connected to a gate (G) of the transistors. One electrode of the capacitor (15) is connected to a cathode of the diode (14), and the other electrode is connected to an emitter (E) of the transistors.
