What does a commonly used low-power DC stabilized power supply system consist of: power transformer, rectifier circuit, filter circuit, voltage stabilizing circuit
Overview of a small-power DC stabilized power supply system:
p>The low-power DC regulated power supply system refers to a DC regulated power supply with an output voltage ranging from tens to hundreds of volts and an output power ranging from a few watts to several tens of watts. Its main function is to convert alternating current into direct current and maintain the stability of the output voltage to meet the needs of various equipment requiring different working voltages and working environments.
The working principle of the low-power DC regulated power supply system:
The working principle of the low-power DC regulated power supply system is relatively simple. When the input AC signal+ enters the transformer, the AC signal of the required size and frequency is obtained after the transformation ratio adjustment, and is processed by the rectifier bridge, filter capacitor and other components to obtain a smooth DC signal. The DC signal is stabilized by the voltage regulator and then output to the load port. When the load changes, the voltage regulator will automatically adjust its output voltage to maintain the stability of the output port.
Applications of low-power DC regulated power supply systems:
Low-power DC regulated power supply systems are widely used in various electronic equipment, such as computers, communication equipment, medical equipment, etc. They play an important role in these devices and provide necessary power support for these devices.
Voltage stabilizer:
The voltage stabilizer is one of the most important components in the low-power DC stabilized power supply system. Its main function is to keep the voltage of the output port from being affected by changes in input voltage and load to ensure the stability of the output port.
Filter capacitor:
The filter capacitor is a component behind the rectifier bridge. Its main function is to smooth the rectified output signal to eliminate the pulsation component. At the same time, it can also protect the subsequent components from being interfered by high-frequency noise.
Summary:
The low-power DC regulated power supply system is a very important component in the field of modern electronic technology. It provides necessary power support for various electronic devices by converting input AC signals into output DC signals and maintaining the stability of its output port. In the future development process,
