FIELD: electricity. ^ SUBSTANCE: transformer includes flat four-pin magnetic conductor the section area of end pins of which is twice as small than the surface area of the pins located between them. Each pin is enveloped with similar primary winding and a group of secondary windings. Windings enveloping one end pin are connected in series and in keeping with similar windings enveloping the other end pin. Group of secondary windings includes two opposite secondary windings with number of loops Nk0, two secondary windings with number of loops Nk1 and two like opposite secondary windings, two secondary windings with number of loops Nk2 and two like opposite secondary windings, two secondary windings with number of loops Nk3 and two like opposite secondary windings, where: N - maximum number of loops, and k0=1, k1=(1+1/31/2)/(2cos15), k2=1/31/2, k3=1/(231/2cos15). Each secondary winding wound in keeping with or opposite one pin is consequently connected to the secondary winding of the other pin and to the secondary winding of the third pin, thus forming zigzag connection the free outputs of which are outputs of transformer. ^ EFFECT: simplifying the construction and improving reliability. ^ 4 dwg, 1 tbl |
