Overview
Active filter (APF) multiple, multi-level PWM technology, single capacity can reach 300A
Most of the widely used loads are non-linear loads, such as rectifiers, inverters, UPS, elevators, air conditioners, energy-saving lamps, copiers, household appliances, etc. These non-linear loads will generate a large amount of harmonic currents and inject them into the power grid, distorting the voltage waveform, and causing serious harm to the power grid and all back-end users. In addition, impulsive and fluctuating loads, such as electric arc furnaces, welding equipment, etc., not only generate a large number of high-order harmonics during operation, but also cause power quality problems such as voltage fluctuations, flicker, and three-phase imbalance, which seriously affect Improve the efficiency of electrical energy use.
NAP series active filter APF can filter 2~50 harmonics dynamically and in real time, with an effective filtering rate of 95%, fast control of flicker and voltage fluctuations, and strong expansion capabilities. Filters of different capacities can be mutually expanded. Allows users to develop more flexible harmonic control schemes.
Features

2. The faulty module does not affect the operation of the normal module, and can be replaced with power, with high reliability
3. It can dynamically filter out 2~50 harmonics in real time, and the effective filter rate can reach 95%
4. The full response time is less than 10ms
5. Better control of flicker and voltage fluctuation
6. Unique ripple self-elimination technology, small ripple
7. High stability, design life of 20 years
Application field
1: Power system in areas with large grid harmonics, such as factories, enterprises, etc.
2: Production enterprises that use high-power nonlinear loads and shock loads (such as air pumps, etc.)
3: Power systems that require high power grid quality, such as hospitals, etc.
4: Power consumption system that needs comprehensive compensation for reactive power, harmonics and three-phase unbalance
5: The original equipment modification site or the site where it is required to be installed in combination with the switch cabinet
