What categories can DC stabilized power supplies be divided into based on their working methods?
A DC regulated power supply is an electronic device that can provide stable DC power to the load. Most of the power supplies of DC stabilized power supplies are AC power supplies. When the voltage of the AC power supply or the load resistance changes, the DC output voltage of the regulator will remain stable. At work, DC regulated power supplies can be divided into the following three categories:
1. Controlled rectifier switching regulated power supply: thyristor is used as the adjustment switch, and the power is supplied directly from the AC mains power grid or after being stepped down by a transformer. The output voltage is adjusted by changing the conduction time of the thyristor to achieve the purpose of stabilizing the output voltage.
2. Chopping type switching regulated power supply: Its input is an unstable DC voltage. It changes the on-off ratio of the switching circuit and obtains a one-way pulsating DC at the output end. After filtering, a stable DC voltage that is different from the input voltage is obtained. .
3. Converter-type switching regulated power supply: The unstable DC voltage is sent to the inverter to convert it into high-frequency AC, and then the new DC output voltage is obtained after transformation, rectification and filtering. The output voltage is sampled and the inverter is controlled by feedback. The operating frequency of the inverter is adjusted to achieve the purpose of stabilizing the output voltage.
The advantages of switching-type regulated power supply are high efficiency, small size and light weight; the disadvantage is that the circuit is relatively complex and there is a certain amount of electromagnetic interference. As a programmable DC power supply manufacturer, Xinnuoer Technology can provide DC power supply, DC regulated power supply, programmable DC power supply, program-controlled DC power supply, programmable power supply, program-controlled power supply, etc., program-controlled DC power supply.
