As a kind of power conversion machinery and equipment, rail switching power supply can often be seen in our daily life. As everyone knows, most people have very little understanding of its basic knowledge and functions. Here, people will take you to master the basic knowledge and functions of switching power supply.
The rail switching power supply is a small and medium-sized handheld converter advanced equipment, which is generally composed of a casing, a power switch, a toroidal transformer and an inverter circuit. It can be divided into AC output type and DC output type. Generally, there are two types of software embedded wall and desktop type. It is generally used to move mobile phones, cameras, computers, arcade game consoles and other electronic devices.
The standard switching power supply in our country is 220V alternating current, and most of the commonly used low-power electronic equipment cannot bear that working voltage. Therefore, power conversion equipment must convert 220V alternating current into a working voltage that can be accommodated by various electronic equipment. Switching power supply is the existence of such an electronic equipment power conversion equipment.
According to modern electronic technology, the switching power supply is turned off in the above-mentioned way of manipulating power components, which promotes the amount of current that is normally output from everything. The above-mentioned core prefabricated components are the pulse width modulation (PWM) control IC and MOSFET of the rail switching power supply. Following the development trend of modern electronic technology, the technical nature of the switching power supply is also constantly developing and upgrading. Switching power supplies reflect environmental protection, energy saving, high efficiency, low cost and convenience are people who seek perfection. Switching power supplies have been widely used in various electronic equipment. It is obvious that power switching power electronic components have long become an indispensable part.
Rail switching power supplies can be divided into two types: DC switching power supplies and AC switching power supplies.
Among the two types of rail switching power supplies here, AC switching power supplies are used in daily life at least, and are not common, so this type of main DC switching power supply is connected in small series. The DC switching power supply has a great advantage. It can convert the output driving force and transmit the rough working voltage into the DC working voltage (fine) that takes the body components into consideration. The key component of the DC switching power supply is the DC/DC converter. It is also because of this key composition that the DC switching power supply can convert coarse electricity into fine electricity. Therefore, the DC/DC components can also be said to be a key reason for distinguishing between the DC power switch and the AC power switch.
