DC-DC converter last time has gained close attention in the environment of radio amateurs. The DC-DC boost converter simplified the development of many charger circuits for various gadgets. Now even a novice electronics engineer is able to independently make a "charge" for his smartphone or tablet. Now you can easily convert the voltage from solar panels to a voltage of almost any level. If it is necessary to reduce the voltage of the power source, then a DC-DC buck converter comes to the rescue.
There are a lot of videos on this topic available on the network, one few of them talk in detail about the device and the principle of the operation of such devices. Therefore, the purpose of this video is to fill this gap and more subtly to study the principle of the DC-DC converter.
During the presentation of the material, the purpose of each element in the circuit is described in detail: a capacitor, an inductor, a diode. The principle of constructing a control system for a transistor is also touched upon. It is told about the features and how the down-and-up DC-DC converter works and works.
