ABSTRACT:
An inverter-driven induction motor system having input lines (12,14,16) for receiving a three-phase ac input signal which is converted into a dc signal and transmitted on dc bus lines (24,26) before gated into a three-phase alternating current output signal transmitted to the motor on output lines (34,36,38). A four winding common mode inductance (L1) is connected on the output side with an inductance connected to the motor ground wire (42). A ground wire choke (Lg) is also added to further reduce conducted emitted radio frequency noise or interference. A third order filter and grounding capacitance (C14,C15,C16) are further added to the ac input side to improve EMI performance.
