ABSTRACT:
An electric leakage preventive apparatus comprises an equivalent impedance which is equivalent to a load leakage impedance of a load in a main body; a switching unit for applying voltage to the equivalent impedance; a driving unit for driving the switching unit; and a control unit for generating a switching pattern. The leakage preventive apparatus is capable of simply and surely preventing leakage current since the earthing current is canceled by applying an anti-phase voltage to the equivalent impedance.
