Active Power Filter(APF)
Modular design, any module failure will not affect the normal work of other modules, greatly improve the reliability of the whole equipment; It can realize smooth expansion of multiple units running directly in parallel. When multiple devices are added, the master/slave control mode is adopted. When multiple modules are connected in parallel, all modules can share a set of current transformer; It can filter the odd harmonic current below 2~50 times at the same time, and can set the harmonic subsegment that needs 13 kinds of filtering according to the need. When the load current distortion rate is greater than 20%, the filtration rate is not less than 85%; When the load current distortion rate is less than 20%, the filtration rate is not less than 75%
