Litsamaiso tsa motlakase tsa elektroniki koloing ea motlakase (EV) li na le mefuta e mengata ea li-capacitor.
Ho tloha ho di-capacitor tsa DC-link ho isa ho di-capacitor tsa polokeho le di-capacitor tse sa hlokeng tlhahisoleseding, dikarolo tsena di bapala karolo ya bohlokwa ho tsitsiseng le ho sireletsa di-elektroniki dinthong tse kang ho phahama ha motlakase le tshitiso ya motlakase (EMI).
Ho na le topology tse 'ne tse kholo tsa li-inverter tsa traction, tse nang le liphapang tse ipapisitseng le mofuta oa switch, voltage le maemo. Ho khetha topology e nepahetseng le likarolo tse amanang le eona ho bohlokoa haholo ho raleng li-inverter tsa traction tse fihlelang litlhoko tsa ts'ebetso ea hau le litšenyehelo.
Jwalo ka ha ho boletswe, ho na le di-topologi tse nne tse sebediswang haholo ho di-inverter tsa ho hula ha motlakase wa EV, jwalo ka ha ho bontshitswe ho Setshwantsho sa 2.

Li-topologi tsena li oela likarolong tse peli: Li-Powertrain tsa 400V le Li-Powertrain tsa 800V. Pakeng tsa lihlopha tsena tse peli, ho tloaelehile haholo ho sebelisa li-topologi tsa "maemo a 2". Li-topologi tsa "maemo a mangata" li sebelisoa lits'ebetsong tse phahameng tsa motlakase tse kang literene tsa motlakase, literene le likepe empa ha li ratoe haholo ka lebaka la litšenyehelo tse phahameng le ho rarahana.

Li-capacitor tsa Snubber– Ho fokotsa motlakase ho bohlokwa ho sireletsa dipotoloho ho tloha ho di-spikes tse kgolo tsa motlakase. Di-capacitor tsa snubber di hokela ho node ya switching ya motlakase o phahameng ho sireletsa di-elektroniki ho tloha ho di-spikes tsa motlakase.

Li-capacitor tsa DC-Link– Litšebelisong tsa motlakase, Li-capacitor tsa DC-link li thusa ho fokotsa litlamorao tsa inductance ho li-inverter. Li boetse li sebetsa e le li-filter tse sireletsang litsamaiso tse nyane tsa EV ho tloha ho spikes ea motlakase, ho phahama ha motlakase le EMI.
Mesebetsi ena kaofela e bohlokoa haholo bakeng sa polokeho le ts'ebetso ea li-inverter tsa traction, empa moralo le litlhaloso tsa li-capacitor tsena lia fetoha ho latela hore na u khetha topology efe ea inverter ea traction.
