Abstract
To suppress a leakage current flowing through a parasitic capacitor of an insulated transformer of a high-side insulated power. The present invention suppresses a common mode current using a common mode reactor by focusing on the fact that a leakage current flowing through a parasitic capacitor of an insulated transformer of a high-side insulated power source resulting from a high-frequency signal generated due to an on/off operation of a high-side switching element is the common mode current. The common mode reactor reduces the common mode current and bears the high-frequency signal to prevent the high-frequency signal from being applied to the insulated transformer of the high-side insulated power source, suppress the leakage current flowing through the parasitic capacitor of the insulated transformer, and reduce an erroneous operation of the high-side switching element generated due to the leakage current flowing through the parasitic capacitor of the insulated transformer.
