Abstract
The solution deals with rapid and complete discharge of the main switching transistor base of self-vibrating power adjustable transformers with feedback winding. The gist of the solution lies in the fact that the main switching transistor base connects with the complementary circuit, which is formed by the first control PNP transistor and second control NPN transistor with the dynamic inner positive binding. The connection enables miniaturization of the power supply for smaller electric devices, such as chargers of accumulator batteries, computer power supplies, power supplies of direct-current motors with efficient stabilization control.<IMAGE>
