The single-phase voltage stabilizer is composed of a contact auto-coupling voltage regulator, a drive rectifier circuit, an automatic control circuit, etc. The working principle is: when the grid voltage is unstable or the load changes, the automatic sampling control circuit sends out a signal and ......
Read MoreThe backup time is the maximum power supply time that the UPS power supply can provide to the computer and other equipment after the mains power failure. The greater the main power of the equipment you bring, the shorter the actual power supply time. The backup time refers to the maximum power suppl......
Read MoreI think everyone has seen transformers, especially those who are engaged in circuits. Transformers are very important components in industrial and living circuits. Of course, transformers also have many classifications, and they are all called different names. It is applicable to different scenarios......
Read MoreAt present, the suppression of harmonics in the power grid has become a very important task for the power supply sector. With the development of power electronics technology in recent years, active power filtering has become the most promising filtering method to solve the voltage distortion of the ......
Read MoreThe effective value of the voltage at the input end of the UPS power load circuit (imaginary instantaneous value of the effective value), where the unshaded part is the effective value of the voltage during the mains supply time, and the shaded part is the effective value of the load input during in......
