What are the functional principles and characteristics of linear regulated power supplies?
Everyone should have heard of power supply. Basically, everyone has a power source at home. The power supply can be roughly divided into two parts. One is the commonly used switching power supply in daily life, and the other is the relatively rare linear regulated power supply. Linear stabilized power supply is mainly used for DC power supply and is a low-voltage power supply with relatively fast response speed. What is the functional principle of a linear regulator power supply? Next, we will carefully study the principle, function, and characteristics of linear voltage regulators.
The functional principle of linear stabilized power supply:
The working process of the main circuit of a linear regulated power supply first applies preliminary AC voltage regulation to the input power supply through a preset circuit, and then converts it into DC power. The power is provided through a control circuit and isolated and rectified by the main transformer in a single-chip form. Under the intelligent control of the microprocessor controller, fine tune the linear adjustment element to output an accurate DC voltage source.
1. Linear stabilized power supply, linear stabilized power supply and rectification principle: convert 380VAC to the required DC.
2. The working principle of the preset circuit for a linear regulated power supply is to use relays or thyristor components to preset and adjust the AC or DC input voltage. This reduces the power consumption of linear stabilizing components and improves work efficiency. It also ensures high precision and stability of the output voltage source.
3. The working principle of linear regulated power supply and linear regulating components is to adjust the filtered DC voltage to achieve the required value and accuracy of the input voltage.
4. The working principle of linear regulated power supply and filtering circuit is to ensure the output voltage of the DC power supply, and to block and absorb the pulsating waves, interference, and noise of the DC power supply to the maximum extent possible. Less ripples, less noise, less interference.
5. The functional principle of linear regulated power supply and microcontroller control system: The microcontroller controller compares, evaluates, calculates, analyzes and processes various recognized signals, and issues corresponding control instructions to enable the regulated power supply and system to work normally, reliably and harmoniously.
6. Linear stabilized power supply, auxiliary power supply, reference voltage source. Functional principle: Provide high-precision reference voltage source and power supply required for the electronic circuit of DC stabilized system.
What is the function of a linear stabilized power supply? What is the function of a linear stabilized power supply? Linear stabilized power supply is a power supply that was used relatively early after the Industrial Revolution and is a DC stabilized power supply. It is mainly used to stabilize current and voltage, and has the function of reducing voltage output. The response speed of linear regulated power supply is relatively fast, the output ripple is small, and the noise generated during operation is small, but the efficiency is low. The main function of a linear voltage regulator is to stabilize the voltage. When a DC voltage flows, it produces a low voltage output, making it a relatively safe power source.
