Using filter module components. At present, there are many filter modules or modules specially used to resist conduction interference in the market. These filters have strong interference ability, at the same time, they also have the interference transmission to the power supply, some also have the

Polyphase pulse rectifier. The method of polyphase rectification can be adopted when the condition allows or requires the harmonic to be limited in a relatively small way. The 12-phase pulse rectifier THDV is about 10 to 15 and 18 phase pulse rectified, the THDV of which is about 3 to 8, meeting the

Equipped with source power filter. In addition to the traditional LC filter is still in use, an important trend of harmonic suppression is the use of active power filter. In series or parallel to the main circuit, the harmonic current is detected from the compensation object in real time, and the co

Installation of appropriate reactor. The input power factor of the converter depends on the AC-DC conversion circuit system inside the device. The parallel power factor can be used to correct the DC reactor, and the power side of the AC reactor can be connected in series. The THDV of the incoming cu
