<p>A leakage current reduction device (43) for supplying a common mode current (J1) and same phase current (J3) from connection lines (92) to a comparator (41) through capacitors (21) through (23) by having a common mode transformer (1) detect, as a common mode voltage (V1), the common mode current (J1) flowing from an AC power source (40) to connecting lines (92), and converting the common mode voltage (V1) to an alternating current component (V4) through a filter device (6), a voltage amplifier (3), and capacitor (8), and through the amplifier (3) and the capacitor (8), and supplying the alternating current component (V4) to neutral points (2N) of the Y-connected capacitors (21) through (23) in the same phase as the common mode voltage (V1).</p> |
