Abstract
Systems, devices, and methods including a first drive winding wound on a first core, where the first drive winding may be driven with a first input signal; a second drive winding wound on a second core, where the second drive winding may be driven with a second input signal, and where the second input signal has an opposite polarity of the first input signal; a first comparator configured to receive a first drive signal from the first drive winding; a second comparator configured to receive a second drive signal from the second drive winding; and a processor configured to receive the output signals from the first comparator and the second comparator, determine a saturation status of the first core and the second core, and determine a potential leakage signal based said saturation status of the first core and the second core.
