What is the internal working effect of the new military custom power supply

Military custom power supplyIt is a common power product in life, and it is used in many areas in life. But how much do we really know about it? After investigation, the editor found that many people have never understood it carefully.

In fact, for it, the aspect worthy of our understanding is the circuit. Generally, it has two functions: a through protection circuit and an overcurrent protection circuit. For the former, the full-bridge and half-bridge are commonly used topologies for switching power supplies, and pass-through poses a great threat to it. It is the phenomenon that two transistors on the same bridge arm are simultaneously turned on at the same time. During the commutation period, the switching power supply is susceptible to interference and causes a direct current. Excessive direct current will damage the power electronic devices used for the inverter. Once the through phenomenon occurs, it must be detected as soon as possible and the drive must be turned off immediately to avoid the PN junction of the switching device from accumulating excessive heat and causing burnout.

Of course, it has the advantages of complete functions and wide range of uses, and the main point is its energy-saving and convenient features. In the production and design of power management circuits, it is helpful to have a basic understanding of heat transfer before investigating heat dissipation issues. First of all, heat is a type of energy that will be transferred due to the temperature difference between the two systems. Heat transfer takes place in three ways: conduction, convection and radiation. When a high-temperature device comes into contact with a low-temperature device, conduction occurs. The high-amplitude high-temperature atoms collide with the atoms of the low-temperature material, thereby increasing the kinetic energy of the low-temperature material. This increase in kinetic energy causes the temperature of the high-temperature material to rise and the temperature of the low-temperature material to drop.

The above content is the internal working effect of the new military customized power supply explained by the editor. Hope it will be helpful to everyone in understanding this kind of products.
