What is the functional principle of linear voltage stabilized power supply and its characteristics?
Everyone should have heard of power supplies. Basically everyone has a power supply in their home. Power supplies can be roughly divided into two parts. One is the switching power supply, which is commonly used in daily life, and the other is the relatively rare linear regulated power supply. Linear regulated power supply is a low voltage power supply that is mainly used for DC power supply and is relatively fast in response. What is the functional principle of linear regulated power supply? Next, we will take a closer look at the principle, function, and characteristics of linear regulated power supplies.
Functional principle of linear regulated power supply:
The working process of the main circuit of a linear regulated power supply begins with the initial AC voltage stabilization of the input power supply through a preset circuit, which is then converted to DC. The power supply is provided through a control circuit and in monolithic form through isolation and rectification of the main transformer. Under the intelligent control of the microprocessor controller, the linear adjustment element is fine-tuned to output an accurate DC voltage source.
1, linear regulated power supply, linear regulated power supply and rectification principle: 380VAC will be converted to the required DC.
2, linear stabilized power supply, preset circuit principle of operation: the use of relays or thyristor components to preset and pre-set the AC or DC input voltage. This reduces the power consumption of the linear stabilizing components and improves efficiency. It also ensures high accuracy and stability of the output voltage source.
3、Linear stabilized power supply, the working principle of linear regulating components: regulate the filtered DC voltage in order to make the input voltage reach the required value and accuracy requirements.
4、Linear regulated power supply, the working principle of the filter circuit: to ensure the output voltage of the DC power supply, maximize the blocking and absorption of the pulsating wave, interference and noise of the DC power supply. Less ripple, less noise, less interference.
5, linear regulated power supply, microcontroller control system function principle: microcontroller controller compares, evaluates, calculates, analyzes and processes various identified signals, and issues the corresponding control instructions so that the regulated power supply voltage regulator system can work normally, reliably, and coordinately.
6, linear regulated power supply, auxiliary power supply, reference voltage source function principle: to provide dc voltage regulator system electronic circuits required for high precision reference voltage source and power supply.
What is the function of linear regulated power supply? What is the function of linear voltage stabilized power supply? The linear regulated power supply is a relatively early power supply used after the industrial revolution and is a DC regulated power supply. It is mainly used to stabilize the current and voltage, and has the function of reducing the 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 regulated power supply is to stabilize the voltage. It produces a low voltage output when DC voltage flows, making it a relatively safe power supply.
Characteristics of Linear Regulated Power Supplies
Since a linear regulated power supply is a type of voltage stabilized power supply, it has low output voltage characteristics and can convert DC voltage to low voltage output. At the same time, the linear regulated power supply unit responds faster than a typical power switch and can output a smaller ripple. When using the same power supply, linear regulated power supplies produce relatively low noise. Since linear regulated power supplies use relatively large resistors, the efficiency decreases with decreasing voltage and generates relatively large amounts of heat, making them relatively inefficient.
