In this video, I explain in sufficient detail how exactly the circuit of the simplest pulse power supply works, it is also a phone charger, which has one bipolar transistor in its composition. This circuit of a pulse phone charger is used very often, and to repair it, in case of a breakdown, it would be nice to know what exactly the operating principle of this circuit has. And in addition to the general operation of the circuit of this simplest phone charger, I also explain the functional purpose of each of its electronic components. As a result, after watching this video, even a beginner will understand and understand how exactly the circuit of this pulse power supply functions.
