POWER CIRCUIT OF ELECTRIC POWER INVERTER Russian patent published in 2002 - IPC

FIELD: DC- to-ac power inverters. SUBSTANCE: power circuit is designed for use in dc-to-ac inverter incorporating semiconductor modules and connecting buses arranged as follows relative to semiconductor module as they recede from the latter: positive bus, ac bus, and negative bus or negative bus, ac bus, and positive bus. Proposed design does not need through hole in adjacent bus for passing bolts used when respective buses are bolted to semiconductor module leads and therefore this point of bus does not need special insulation. EFFECT: reduced inductance of inverter power circuit. 16 cl, 26 dwg
