Selelekela saInverter
Inverter ke sesebelisoa sa elektroniki se fetolang motlakase o feto-fetohang hore e be oa hona joale o tobileng, haholo-holo se sebelisetsoang ho fana ka matla ho mojaro.Inverter ke sesebelisoa se fetolang mohloli oa motlakase oa DC hore e be mohloli oa motlakase oa AC.E ka sebelisoa ho microcomputer kapa tsamaisong e le 'ngoe ea chip microcomputer hammoho le lisebelisoa tsa ts'ebetso ea matšoao.
Li-inverterse ka aroloa ka li-inverters tsa mekhahlelo e le 'ngoe, tse tharo le tse tletseng borokho ho ea ka matla a matla.Mokhahlelo o le mong le li-inverters tsa mekhahlelo e meraro li entsoe ka li-transformer, li-filters le li-filters tsa LC, 'me tlhahiso ea waveform ke sine wave;li-inverters tse nang le borokho bo felletseng li entsoe ka seketsoana sa "rectifier filter", "Schottky diode" (PWM) le potoloho ea koloi, 'me sebopeho sa wave wave ke square wave.
Li-inverterse ka aroloa ka mefuta e meraro: mofuta o tsitsitseng oa ho tima, mofuta oa taolo ea sebaka se shoeleng (tsela ea sine wave) le mofuta oa taolo ea switjha (tsela ea square wave).Ka nts'etsopele ea mahlale a elektroniki a matla, li-inverters li sebelisoa haholo mafapheng a fapaneng.

Inverter ke sesebelisoa sa elektronike sa matla se fetolang motlakase o otlolohileng hore e be oa motlakase o mong.Inverter e na le potoloho ea filthara ea rectifier, potoloho ea Schottky diode (SOK) le potoloho ea koloi.
Inverter e ka aroloa ka inverter e sebetsang le inverter e sebetsang, passive inverter, eo hape e tsejoang e le inverter circuit kapa voltage regulator circuit, ka kakaretso ka sethala sa ho kenya, sethala sa bohareng (LC), sethala sa tlhahiso (rectifier), joalo-joalo, le inverter e sebetsang ke phetoho ea lets'oao la motlakase ho fumana motlakase o tsitsitseng oa DC.
Inverter e sa sebetseng hangata e na le capacitor ea matšeliso borokhong ba rectifier, athe inverter e sebetsang e na le inductor ea filthara borokhong ba rectifier.
Potoloho ea inverter e na le melemo ea boholo bo nyane, boima bo bobebe, ts'ebetso e phahameng joalo-joalo.Ke karolo ea bohlokoa ea mefuta eohle ea lisebelisoa tsa motlakase tsa motlakase.

Ho ea ka topology ea inverter e ka aroloa ka: full-bridge inverter, push-pull inverter.
E ka aroloa ka PWM (pulse width modulation) inverter, SPWM (quadrature signal modulation) inverter le SVPWM (space voltage vector modulation) inverter.
Ho ea ka sehlopha sa potoloho ea ho khanna e ka aroloa ka: halofo-borokho, mofuta oa push-pull.
Ho latela mofuta oa mojaro, e ka aroloa ka motlakase oa inverter oa karolo e le 'ngoe, phepelo ea motlakase ea mekhahlelo e meraro, converter ea DC, phepelo ea motlakase ea filthara e sebetsang, jj.
Ho ea ka mokhoa oa ho laola o ka aroloa ka: mokhoa oa hona joale le mokhoa oa motlakase.
