The 28V DC stabilizing power supply is a device that converts 220V or 380V AC power to a stabilized DC voltage output. It must go through four stages: conversion, rectification, filtering, and voltage stabilization. Here are the working principles of the following four links:
Transformer: Converts the system's 220V or 380V AC voltage to the required AC voltage for the rectifying circuit via a step-down transformer. The transformer's turns ratio is determined by the secondary voltage. Transformers: Transformers.
(2) Rectifier and Filter Circuit: The rectifier circuit converts AC voltage Ui into pulsating DC voltage. It is then processed by the filter circuit to eliminate larger ripple components, resulting in a DC voltage U1 with reduced ripple. Common rectifier and filter circuits include full-wave rectifier and bridge rectifier.28V DC Power Supply4,28V DC Voltage Stabilizer Power Supply4,28V Aviation Power Supply2,28.5V DC Power Supply2,7-HK-182 Aviation Battery
(3) Filtering Circuit: By filtering most of the alternating current components from the output voltage of the rectifying circuit, a relatively smooth direct current voltage can be obtained. Each filtering capacitor C satisfies RL-C = (3~5)T/. For a 2 or medium T input alternating current signal cycle, RL is the equivalent load resistance of the rectifying and filtering circuit.
(4) Voltage Stabilization Circuit: The function of the voltage stabilization circuit is to maintain a stable output of direct current voltage, which remains unchanged regardless of fluctuations in the alternating current power grid voltage or variations in load.
