Inverter for an electric drive of an electric vehicle or hybrid vehicle, modular system and method for manufacturing the inverter

摘要

The invention relates to an inverter (10) for an electric drive of an electric vehicle or a hybrid vehicle comprising a plurality of half bridge modules (11) with power contacts (12, 12',12',12''') and signal contacts (13),where the power contacts (12,12',12',12''') are current-conducting and current-blocking switchable via the signal contacts (13), so that the power contacts (12, 12',12',12''') a direct current can be supplied and output as alternating current and the power contacts (12,12',12',The inverter of the invention (10) is characterized in that the power contacts (12, 12',12',12''') are welded to the busbars (20, 21, 22). The invention further relates to a modular system and a method for producing the inverter.
