How to adjust the voltage and current of a DC stabilized power supply?

Article Source：Kinri Energy | Author：Kinri Energy | Issuing Time：2024.04.03
DC stabilized power supply, as an indispensable and important component of electronic devices, has the characteristic of providing stable and reliable DC voltage and current for circuits. Its voltage and current regulation function is one of its core functions and a key factor in ensuring the stable operation of electronic devices. So, how does a DC stabilized power supply achieve this function?



Voltage regulation mechanism

The voltage regulation mechanism of a DC stabilized power supply mainly relies on its internal voltage regulation circuit. A voltage regulation circuit typically consists of an error amplifier, a voltage feedback network, and a power regulator.

Error amplifier

The main task of an error amplifier is to compare the reference voltage with the actual output voltage and generate an error signal. This error signal will be used to adjust the output voltage in the future.

Voltage feedback network

The function of a voltage feedback network is to feedback a portion of the output voltage back to the error amplifier and compare it with the reference voltage. Through this method, the DC stabilized power supply can monitor the output voltage in real time and adjust it as needed.

Power adjustment tube

The power regulator is a key component for performing voltage adjustment. According to the output signal of the error amplifier, the power adjustment tube will adjust its conductivity, thereby changing the size of the output voltage.

Diversion mechanism

The current regulation mechanism of a DC stabilized power supply mainly relies on its internal current limiting circuit and current regulating circuit.

Current limiting circuit

When the output current exceeds the preset maximum value, the current limiting circuit will intervene to limit the further increase of the current, thereby protecting the power supply and load from damage.

Current regulation circuit

The current regulation circuit is used to precisely control the magnitude of the output current. It usually includes a current sensing element and a current regulator.

Current sensing element

Current sensing components (such as current transformers or shunt resistors) are used to detect the magnitude of the output current and convert it into a voltage signal.

Current regulator

The current regulator adjusts the conductivity of the power adjustment tube based on the output signal of the current sensing element, thereby accurately controlling the magnitude of the output current.

Summary

In summary, the DC stabilized power supply achieves precise control of output voltage and current through its internal voltage regulation circuit and current regulation circuit. This voltage and current regulation function not only ensures the stable operation of electronic devices under various working conditions, but also extends the service life of power and loads. In practical applications, we should choose a suitable DC stabilized power supply according to specific needs and ensure its correct installation and use, in order to fully leverage its advantages of voltage and current regulation.
