    Linear DC Power Supply Working Principle

    The working process of the main circuit of the linear DC power supply is that the input power supply is initially AC stabilized by the pre-stabilizing circuit, and then converted into a DC power supply through the isolation and rectification of the main working transformer, and then under the intelligent control of the control circuit and the single-chip microprocessor controller. The linear adjustment element is finely adjusted to output a high-precision DC voltage source. The linear DC power supply products can be widely used in scientific research, colleges and universities, laboratories, industrial and mining enterprises, electrolysis, electroplating, charging equipment, etc.

    What are the components of linear DC power supplies?

    Power transformer

    Power transformer is a kind of soft magnetic electromagnetic element, whose functions are power transmission, voltage conversion and insulation isolation, and has been widely used in power supply technology and power electronics technology.

    Rectifier circuit

    A rectifying circuit is a circuit that converts alternating current electrical energy into direct current electrical energy. Most rectifier circuits are composed of transformers, rectifier main circuits and filters. It is widely used in DC motor speed regulation, generator excitation regulation, electrolysis, electroplating and other fields. The rectifier circuit usually consists of the main circuit, filter and transformer.

    Filter circuit

    The filter circuit is often used to filter the ripple in the rectified output voltage, and is generally composed of reactive components, such as a capacitor C in parallel with the load resistance, or an inductor L in series with the load, and various complexes composed of capacitors and inductors.

    Regulator circuit

    A voltage regulator circuit refers to a circuit that can keep the output voltage constant when the input voltage, load, ambient temperature, circuit parameters, etc. change. This circuit can provide stable DC power and is widely used in various electronic equipment.
