At 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......
Read MoreThe most obvious point of the function of the voltage stabilizer is that it can control the output voltage of electrical appliances with large current fluctuations within a fixed value range to ensure the smoothness of the circuit and the normal use of the electrical appliances.
Read MoreUPS parallel function and method, and the application of parallel technology in UPS system. At present, many companies have not selected the best connection method according to the actual situation in the process of choosing the UPS connection method, which has caused the whole system to have large ......
Read MoreI believe that everyone is not very familiar with voltage regulators, but it plays a big role in our homes. It can automatically adjust the output voltage of the power supply equipment, so that the unstable power supply voltage with large fluctuations can be stabilized in the corresponding range, so......
Read MoreThe frequency converter transforms the alternating current in the mains from AC→DC→AC, and outputs a pure sine wave. The output frequency and voltage can be adjusted within a certain range. It is different from the frequency conversion speed controller used for motor speed control, and it is also di......
