Abstract
Devices, systems, and methods are disclosed for reducing leakage current in power converters, such as for HVAC systems, to facilitate compatibility with GFCI devices. In various embodiments, the power converter may include components to filter and/or reduce common mode noise, such as by removing high frequency components of the common mode noise, while maintaining leakage current below a trip threshold of a GFCI device.
