POWER CONVERTER

PROBLEM TO BE SOLVED: To provide a power converter having a structure that can be made compact. SOLUTION: A connecting point 96 between a snubber capacitor 72 and a snubber diode 74 of a snubber module 64 connected in parallel to an IGBT 12 and a connecting point 98 between a snubber capacitor 84 an...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a power converter having a structure that can be made compact. SOLUTION: A connecting point 96 between a snubber capacitor 72 and a snubber diode 74 of a snubber module 64 connected in parallel to an IGBT 12 and a connecting point 98 between a snubber capacitor 84 and a snubber diode 86 of a snubber module 68 connected in parallel to an IGBT 16 are connected to each other, with snubber resistors 102 and 104 inserted on the respective sides. Between one ends of the snubber resistors 102 and 104 and a circuit on the positive electrode side of the IGBT 12, a snubber common resistor 106 is inserted. COPYRIGHT: (C)2010,JPO&INPIT
