The intelligent load optimization based safety system in electrical television network based on the starting loads

One of the most interesting aspects of televisions is this type - pulse source electricity, very light and compact, when in good condition, gives good output characteristics. This article describes how to build a power source based on the MP-3-3. If you are engaged in repairing the USCD, you should know that if the MP-3-3 is plugged into the network without load, it will not work. A safety system is activated, which monitors not only overload, but also “under load”. Therefore, in order to use the MP-3-3 as a laboratory, that is, with various loads, it must be loaded. The proposed to load each MP-3-3 output sources with starting loads, but, as practice shows; There is no need to do so. The fact is that the protection system does not monitor the currents in all the secondary windings of the pulse transformer. It is important for her to get the volume in the second round. Then, for any second round, it doesn't matter. In addition, to bring the source into stabilization mode, it must be loaded with at least 20W, and with the resistance of the resistors indicated in L.1, in total, no more than 3–4 W is obtained. Bring the source to operating mode, this is not enough.
