Abstract
An embodiment of an outdoor unit of a climate control system includes a refrigerant compressor, an electric motor configured to drive the refrigerant compressor, and a variable frequency drive (VFD) electrically coupled to the electric motor and configured to be electrically coupled to a ground-fault circuit interrupter (GFCI). The GFCI is electrically couped to an electrical power source. The VFD has circuitry that includes an electromagnetic interference (EMI) filter configured to at least partially filter electromagnetic interference generated by the VFD, and an inductive device that is configured to be electrically coupled to the GFCI in parallel with the EMI filter. The inductive device is configured to at least partially dissipate current discharged from the EMI filter in response to a de-energization of the electrical power source, to thereby prevent a trip of the GFCI upon re-energization of the electrical power source.
