Fig. 1. The  pulse converter of the voltage. The circuit

The given converter of a voltage allows to connect loading capacity up to 100 W. Idling the current consumed by the converter, does not exceed 0,5 A. Range  of entrance voltage 9-15 V. Working frequency of the converter about 20 kHz.

  The transformer is made of two magnet -wires  combined together from ferrite of mark М2000НМ1 standard size К32х20х6. The data of windings are specified in the table.

At manufacturing the transformer the secondary winding all over again is reeled up. Winding is carried out a coil to a coil, in one layer with the subsequent isolation fluorine -layer  or another isolation a material. The primary winding is reeled up by two wires simultaneously (in regular intervals having distributed coils on core).

  Transistors are established on a massive radiator (than it is better than themes more).
