The active filter launched by Bogmating for domestic grid users, as an advanced power treatment product with high technology content, integrates the power electronic technology, digital control technology, digital signal processing technology and other cutting-edge technologies. The product is composed of power converter circuit and harmonic detection algorithm. The key technology of the power electronic converter circuit is the selection and realization of topological structure.

As a product of dynamic filtering of harmonic current, the active filter is characterized by comprehensive filter effect, active filtering of higher harmonics and effective suppression of resonance, so the filter capacity is a key parameter of active filter products. The active filter launched by Bogmating can select to filter each harmonic current within 2 ~50 times once or customize filtering of the harmonic current of the system within 50 times. This technology has two advantages:

First, a compound filter can be constituted by an active filter and a passive filter for the system with huge harmonic current capacity. The passive filter is used to filter the large-capacity and stable lower harmonic current, while the active filter is used to filter the complex higher harmonic current and suppress resonance of the harmonic current.

Second, customize filtering for the harmonic current frequency distribution features to obtain better filter effect and system stability within the fixed capacity.
