ABSTRACT:
A low noise, compact and low cost electric power converter employing a compact common mode transformer, and incorporating a line filter can reduce a leakage current, and can maintain predetermined leakage current reduction effect even if installation condition of the electric power converter or a characteristics of a semiconductor switching element is varied. The electric power converter including a capacitor, a first electrode, a second electrode, a first magnetic body, on which the first electrode and the second electrode are wound to form an LC composite element, connecting electrodes electrically connected to respective of both ends of the first and second electrodes, a second magnetic body for interlinking both ends of the first magnetic body, a coil wound around the second magnetic body in the same winding direction as the first and second electrodes wound around the first magnetic body and a resistor for shorting the output of the coil.
