MOTOR CONVERTER CIRCUIT FOR AN ELECTRIC DRIVE MOTOR AND ELECTRIC DRIVE DEVICE HAVING SUCH A MOTOR CONVERTER CIRCUIT

摘要

An electric drive device (1) comprises a motor converter circuit (3) according to the invention, which has an intermediate circuit capacitor (16). The intermediate circuit capacitor (16) comprises a parallel circuit of a plurality of ceramic capacitors (24). The ceramic capacitors (24) have a lower dissipative resistance and enable better heat dissipation so that the motor converter circuit (3) has a relatively longer service life.
