摘要:
An inverter circuit includes an IGBT (3) and an IGBT (4) connected in series between a power supply potential (Vcc) and a GND potential, and an HVIC (1) and an LVIC (2) for respectively controlling actuation of the IGBTs (3) and (4). The inverter circuit also includes a capacitor (5), a diode (6), and a resistor (7). The capacitor (5) is connected between a terminal (VS) and the GND potential. The diode (6) has a series connection to the capacitor (5) between the terminal (VS) and the GND potential, with such a polarity that a forward current flows from the GND potential to the terminal (VS). The resistor (7) is connected in parallel to the capacitor (5).

摘要:
A power semiconductor module has a detector for detecting main circuit current passing through a power semiconductor element. The detector includes first and second circuit patterns; a bonding wire connected at first and second bonding points with the first and second circuit patterns, respectively; and a pair of terminal patterns extended from near the first and second bonding points of the first and second circuit patterns. The detector is designed to detect a potential difference between the pair of terminal patterns generated by flowing main circuit current through the first circuit pattern, the bonding wire and then the second circuit pattern, in order to detect a potential difference across the bonding wire.

摘要:
Among first IGBTs and first MOSFETs, a transistor arranged near a first gate control circuit gives, through a gate thereof, a gate control signal supplied from the first gate control circuit to a gate of a transistor arranged at a position farther from the first gate control circuit. Among second IGBTs and second MOSFETs, a transistor arranged near a second gate control circuit gives, through a gate thereof, a gate control signal supplied from the second gate control circuit to a gate of a transistor arranged at a position farther from the second gate control circuit.

An inverter module includes a plurality of leads arranged according to a ZIP. A lead (101U, 101V, 101W) serving as a load side output terminal and a lead (104U, 104V, 104W) serving as a high-potential side control input terminal are bent toward directions opposite to each other. A lead (107U, 107V, 107W) serving as a low-potential side control input terminal is arranged at a distance four times a terminal pitch from the lead serving as the load side output terminal (101U, 101V, 101W).
