ELECTRIC HEATING APPLIANCE WITH AC-LINE FILTER WITH LOW LEAKAGE CURRENT

A power supply includes a filter that attenuates a noise component being transmitted toward a source that supplies an AC current. The filter lacks a capacitor establishing a conductive path for conducting a high-frequency alternating signal, a leakage current, or both to a ground electrode. A rectifier is included, and is disposed electrically between the filter and a load that is to be energized by operation of the power supply. The rectifier converts AC into a rectified signal. The power supply also includes a grounding capacitor that establishes a capacitive, conductive path between an output of the rectifier and a ground electrode that is to be electrically connected to ground. The grounding capacitor is electrically separated from the filter by the rectifier, and extends electrically between the ground electrode and at least one of: a positive DC bus conductor from the rectifier, and a DC bus return to the rectifier.
