Frequency converter yog lub tshuab AC lub zog uas hloov hluav taws xob muab rau ntau zaus. Thaum xyoo 1980s, Tuam Tshoj pib siv lub tshuab hloov pauv ntau zaus. Vim tias nws lub zog txuag kev cuam tshuam thiab kev ua tau zoo kawg, kev siv cov zaus hloov pauv txuas ntxiv mus rau sab saum toj jab hauv Suav teb, thiab nws kuj tseem ua txoj haujlwm tseem ceeb hauv kev hloov pauv ntawm kev lag luam ib txwm muaj, enchancment ntawm qhov system ntws, enchancment ntawm automation qib, hluav taws xob txuag thiab lwm yam

Daim ntawv thov

Qhov tseem ceeb ua rau lub zaus hloov pauv yog tias tus tswv xeev hloov pauv zaus tswj hwm qhov nrawm ntawm lub cev muaj zog.

Peb hloov qhov voltage thiab zaus tsis tu ncua alternating tam sim no rau hauv voltage los yog zaus hloov pauv hloov lub tshuab niaj hnub hu ua zaus converter, kev tiv thaiv luv luv, theem-rau-theem luv-circuit tiv thaiv, nkag mus rau ntu tiv thaiv, tso zis ntu tiv thaiv, tiv thaiv overvoltage, kev tiv thaiv undervoltage, kub kev nyab xeeb nkag mus thiab tso zis rov qab kev twb kev txuas tiv thaiv, tswj lub cev muaj zog pib tam sim no, Yog li yog tias koj xaiv los hloov lub pace ntawm AC lub cev muaj zog los hloov qhov zaus ntawm hluav taws xob, koj tuaj yeem ua kom lub zog tuaj yeem tswj tau.
