CPC G01R 31/52 (2020.01) [G01R 19/2509 (2013.01)] | 20 Claims |
1. A system for charging an Electric Vehicle (EV) comprising:
a first drive winding wound on a first core, wherein the first drive winding is driven with a first input signal;
a second drive winding wound on a second core, wherein the second drive winding is driven with a second input signal, and wherein 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, and output a signal based on the saturation of the first core;
a second comparator configured to receive a second drive signal from the second drive winding, and output a signal based on the saturation of the second core; 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, and stop charging the EV if a leakage current based on the determined potential leakage signal exceeds a set threshold.
