Abstract: A fault managed power system (FMPS) measures leakage current in an electronic circuit. The FMPS comprises a source controller, leakage current sensor, pulsing controller, and load end circuit. The source controller generates a pulsing input defining a current-on time interval and current-off time interval. During the current-off time interval, a source driver of the source controller opens a source switch to disconnect power from a power source. The leakage current sensor utilizes a leakage current sensor driver to open a leakage current sensor switch. The pulsing controller utilizes a pulsing driver to close a pulsing switch to provide a return path for leakage current during the current-off time interval. A holdup capacitor at the load end circuit reverse biases a blocking diode to isolate a load from the electronic circuit, such that leakage current flows in the leakage current sensor to enable an accurate measurement of the leakage current.
