To meet the requirements of voltage regulation, DC switching power supplies often need to sample, compare, and amplify the output voltage. During the voltage regulation process, the design typically includes four basic stages: transformation, rectification, filtering, and regulation. Aviation Power Supply
To enhance the safety performance of power sources, it is essential to design a simple and reliable overvoltage and overcurrent protection circuit to prevent damage to load components when voltage and current exceed safe limits. Subsequently, this article will briefly introduce the manufacturing process of a high-power DC switch-mode power supply, focusing on the design of the main circuit, control circuit, and protection circuit.
The main circuit design includes power transformers, rectification circuits, filtering circuits, and voltage regulation circuits.
To ensure that the output voltage of the power supply does not change with the load, the control circuit design should enable the power supply to have feedback adjustment capabilities.
To enhance the reliability and safety of power supply, protection circuit designs often require the implementation of simple protective circuits, such as overvoltage and overcurrent protection. 400Hz power supply
In complex control systems with multiple DC voltage outputs, when a system failure occurs, it is crucial to first ensure that the high-power DC switching power supply's voltage output from each chip or circuit is stable. To avoid the drawbacks of time-consuming, labor-intensive, and inconvenient manual detection, a method to detect the presence or absence of DC voltage output can also be employed.
