Isikhumbuzi esivela kubahlinzeki abakhethekile be-frequency converter embonini yokuphakamisa: Iziguquli ze-Crane frequency ngamadivayisi okulawula amandla asebenzisa ubuchwepheshe bokuguqula imvamisa kanye nobuchwepheshe be-microelectronics ukulawula amamotho e-AC ngokushintsha imvamisa yokuphakelwa kwamandla okusebenza kwemoto. Isiguquli sefrikhwensi sakhiwe kakhulu ngokulungiswa kabusha (AC kuya ku-DC), ukuhlunga, ukuguqulwa (DC kuya ku-AC), iyunithi yokubhuleka, iyunithi yokushayela, iyunithi yokubona, iyunithi ye-microprocessor, njll. Isiguquli sefrikhwensi esisisebenzisa njengamanje sisebenzisa indlela ye-AC-DC-AC, eqale iguqule ukunikezwa kwamandla kagesi e-AC ibe ugesi we-DC ngokusebenzisa isilungisi, bese siguqulela ukunikezwa kwamandla kagesi we-DC nemvamisa ye-DC.
1, Lapho ukhetha isiguquli semvamisa, amaphuzu alandelayo kufanele anqunywe:
1) Umgomo wokwamukela ukuguqulwa kwemvamisa; Ukulawula ukucindezela okungaguquki noma ukulawula kwamanje okungaguquki, njll.
I-2) Uma usebenzisa isiguquli se-frequency ukuze ushayele i-motor enesivinini esikhulu, ukungezwa kwe-harmonics ye-oda eliphezulu kwandisa inani lamanje lokukhipha ngenxa yokusabela okuncane kwe-motor-speed motor. Lapho ukhetha isiguquli semvamisa samamotho anesivinini esikhulu, i-Wuxi Qide Electrical Machinery Co., Ltd. inamandla amakhulu kunokukhethwa kwamamotho ajwayelekile.
