IPC: H02M3/28
Filed: 1990-02-14
Abstract: PURPOSE:To reduce the copper loss of a choke coil by providing a choke coil on the side of an earth line, and winding the windings, which have the line diameters approximately proportional to the sum of output currents, from the one near to the side of an earth terminal, as one winding connected in series so as to constituted the choke coil. CONSTITUTION:When a switching transistor Q1 is turned on by the control of a switching control circuit 1, voltages respectively proportionate to the winding ratio are generated in each secondary winding N2, N3, and N4. As regards the winding N2, a current I11 flows passing all the windings of a choke coil L1, and as regards the winding N2, a current I21 flows passing the windings Wc and Wb of the choke coil L1, and further as regards the winding N4, a current I31 flows passing the winding Wc of the choke coil L1. At this time, the current surely flows the winding whose line diameter is larger, moreover the larger the diameter of the winding is, the more the currents flow, so the current density of the winding disperses effectively.
