The DC power supply is mainly composed of four parts: the power transformer, rectification circuit, filtering circuit, and voltage stabilization circuit.
Power Transformers: Power transformers are soft magnetic electromagnetic components designed for power transmission, voltage transformation, and insulation isolation. They are widely used in power technology and power electronics.
2. Rectifier Circuit "A rectifier circuit" is an electrical circuit that converts alternating current (AC) power into direct current (DC) power. Most rectifier circuits consist of transformers, the main rectifying circuit, and filters, among other components. They are widely used in applications such as speed regulation of DC-powered motors, excitation control of generators, electrolysing, and electroplating. Rectifier circuits typically comprise the main circuit, filter, and transformer.Aviation Power
Since the 1970s, the main circuit has commonly been composed of silicon rectifier diodes and thyristors. Filters are connected between the main circuit and the load to filter out the alternating current components in the pulsating DC power supply. The installation of a transformer depends on the specific situation. The transformer's role is to match the alternating input voltage with the DC output voltage and to provide electrical isolation between the AC grid and the rectifying circuit. The function of the rectifying circuit is to convert the lower AC voltage from the AC step-down circuit into a unidirectional pulsating DC power supply, which is the rectification process of AC. The rectifying circuit is mainly composed of rectifier diodes. After passing through the rectifying circuit, the voltage is no longer AC voltage but a mixed voltage containing both DC and AC components. It is conventionally referred to as unidirectional pulsating DC power supply.36V Aviation Power Supply
3. Filter Circuit
Filtering circuits are commonly used to remove ripple from the direct current (DC) power output of rectifiers, typically composed of inductive components. This includes, for instance, paralleling a capacitor C across the load resistor, or串联 an inductor L with the load, as well as various complex filtering circuits composed of capacitors and inductors.
4. Voltage Stabilization Circuit
A voltage regulator circuit is one that maintains a constant output voltage despite changes in input voltage, load, environmental temperature, and circuit parameters. Such circuits provide a stable DC power supply and are widely used in various electronic devices.400Hz power supply
