  • Patent number: 10139848
    Abstract: A system includes a power source, a power converter, a leakage current cancelation circuit, a load, and a ground node. The power converter is coupled to the power source and supplies the load. During operation of the power converter, a common mode current flows from the load to the ground node via a leakage capacitance. The leakage current cancelation circuit receives at least one signal indicative of the common mode current and generates a leakage cancelation current that is injected into at least one node of the system. The leakage cancelation current has a magnitude opposite a magnitude of the common mode current. For example, the leakage current cancelation circuit receives supply voltage signals output by the power converter, and generates and supplies the leakage cancelation current onto input nodes of the power converter such that a current level on the ground node is between ?3.0 milliamperes and +3.0 milliamperes.
