How does the switching power supply 24V work


Switching power supply 24V manufacturers tell you that the current types of switching power supply are characterized by small size, light weight and high efficiency.

Switching power supply 24V manufacturers tell you that the current types of switching power supply are characterized by small size, light weight and high efficiency. They are widely used in all kinds of electronic equipment. They are indispensable in daily life. Today we are talking about Switching power supply 24V, what does Switching power supply 24V do, what is the principle of Switching power supply 24V, and how it works.

Switching power supply 24V is a type of high frequency inverter switching power supply. Switching power supply 24V, Switching power supply 24V is to use the circuit to control the switching tube to conduct high-speed on and off, and provide AC power to the transformer for transformation into high-frequency AC power, thereby generating the required one or more sets of voltages . The reason for the conversion to high-frequency alternating current is that the efficiency of high-frequency alternating current in the transformer transformer circuit is much higher than 50HZ, so the switching transformer can be made very small, and it is not very hot during operation. The cost is very low. If you don't change 50HZ to high frequency, the switching power supply is meaningless. Switching power supply 24V can be roughly divided into two types: isolated and non-isolated. The isolated type must have a switching transformer, while the non-isolated type may not necessarily have.
Principle of Switching power supply 24V:
1. The AC power input is rectified and filtered into DC;
2. The switch is controlled by a high-frequency PWM (pulse width modulation) signal, and the DC is added to the primary of the switching transformer;
3. High-frequency voltage is induced in the secondary of the switching transformer and supplied to the load through rectification and filtering;
4. The output part is fed back to the control circuit through a certain circuit to control the PWM duty cycle to achieve the purpose of stabilizing the output. When the AC power is input, it generally needs to pass through something like a current loop to filter out the interference on the grid, and at the same time filter the interference of the power supply to the grid; when the power is the same, the higher the switching frequency, the smaller the volume of the switching transformer. But the higher the requirements for the switching tube; the secondary of the switching transformer can have multiple windings or one winding has multiple taps to obtain the required output; generally, some protection circuits should be added, such as no-load, short-circuit protection, etc. Otherwise, the Switching power supply 24V may be burned.
