Abstract
The present invention provides a unique improvement () in an electronic motor drive () having an LC filter () to reduce conducted emissions from a motor (M) back to a voltage source (V). The improvement broadly includes diode () in series with the inductor (L) of said filter to prevent transmission of regenerative power from the motor to said voltage source; and a bypass switch () arranged in parallel with the diode and selectively operable to enable transmission of regenerative power from the motor to said voltage source.
