Abstract
A noise suppressing circuit comprises: windings (W, W) inserted to conductor lines () at respective points (P, P) and coupled to each other through a magnetic core (); a winding (W) coupled to the windings (W, W) through the core (); capacitors () having ends connected to the conductor lines () at respective points (P, P) and the other ends connected to an end of the winding (W); and windings (W, W) inserted to conductor lines () at respective points (P, P) and coupled to each other through a magnetic core (). These components reduce common mode noise. Capacitors () reduce normal mode noise in cooperation with leakage inductances produced by the windings (W, W).
