<p>A small and light weight DC/DC converter is provided comprising a coil in which a first coil (L1) and a second coil (L2) are wound in opposite directions (reversed phases) on the same core is used, and at the same time as when an excitation current is flowed in the first coil (L1) with a switch ON and a switch OFF, an electric current is generated in the second coil (L2) in a direction to offset the magnetization of the core, and the electric current from the second coil (L2) is transferred to an output side capacitor (Cout). Similarly, at the same time as an excitation current is flowed in the second coil with the switch ON and the switch OFF, an electric current (I1) is generated in the first coil (L1) in a direction to offset the magnetization of the core, and the electric current (I1) from the first coil (L1) is transferred to the output side capacitor (Cout). <IMAGE></p> |
