Lefatšeng la kajeno, matla a bekapo le boleng ke lintlha tse mahlonoko tsa khoebo efe kapa efe kapa lehae, lelihlahisoa tsa boleng ba matlaphetha karolo ea bohlokoa ho boloka phepelo ea motlakase e tsitsitseng.Lihlahisoa tsa boleng ba matlajoalo ka Active Harmonic Filters (AHF) e fana ka tharollo ea mantlha mathateng ohle a boleng ba matla a bakoang ke ho fapana, ho feto-fetoha ha motlakase le ho se leka-lekane ha mojaro.Lisebelisoa tsena tse sebetsang hantle, tse sebetsang hantle, tse feto-fetohang, tsa modular le tse theko e tlaase li sebelisoa haholo mecheng ea matla a tlaase kapa a phahameng a matla a matla ho lelefatsa bophelo ba lisebelisoa, ho ntlafatsa ts'epo ea ts'ebetso le ho fokotsa tahlehelo ea matla ho lumellana le litekanyetso tsa boleng ba matla le likhoutu tsa marang-rang.
AHF e fokotsa ho sotha ha waveform, matla a tlase, fluctuation ea voltage le harmonic voltage ka ho kenya motlakase o sothehileng ka amplitude e ts'oanang empa mohato o fapaneng ka nako ea nnete tsamaisong ea matla.Li-filters tsena li ka rarolla tse ling tse 'maloaboleng ba matlamathata ka ho kopanya mesebetsi e fapaneng ka sesebediswa se le seng.Ho etsa bonnete ba hore o fumana molemo ka ho fetisisa lihlahisoa tsena, o lokela ho nahana ka mehato e itseng ea ho itšireletsa.
Pele o kenya AHF, hoa hlokahala ho tseba tikoloho e nepahetseng le ho netefatsa hore e loketse sebaka se itseng.Ho phaella moo, ho boetse hoa hlokahala ho ela hloko maemo a tikoloho ea sebaka sa ho kenya, le ho nka mehato e kang moea oa moea, ho pholisa kapa ho laola mongobo.AHF e hloka motheo o nepahetseng mme ho kengoa ho lokela ho etsoa ke setsebi se lumelletsoeng ho fokotsa kotsi ea liphoso tsa motlakase kapa li-circuits tse khutšoane.
Ho feta moo, ho bohlokoa ho khetha mofuta o nepahetseng oa AHF bakeng sa litlhoko tsa hau tse ikhethileng.Ho na le mefuta e fapaneng ea li-filters ho fihlela litlhoko tse fapaneng.Ka mohlala, li-filters tse ling li ka fana ka ts'ebetso e phahameng lits'ebetsong tsa motlakase o tlaase, ha tse ling li ka sebetsa ka katleho sebakeng se phahameng sa motlakase.Ka hona, ho bohlokoa ho khetha filthara e ka fihlelang litlhoko tsa sistimi ea matla le li-harmonics.
