Invertoare STUDER AJ - DC/AC

 

Invertoarele sunt dispozitive care fac conversia curent continu (DC) in curent alternativ (AC) asigurand calitatea frecventei la 50Hz, deci ele fac conversia tensiunii de 12V, 24V sau 48 V, provenita de la baterii, in tensiune 220Vca. In general exista  doua tipuri de invertoare:

 

-  cu unda perfect sinusoidala (perfomante mult superioare in comparatie cu reteaua conventionala de energie)

-  cu unda sinusoidala modificata (unda este alternativa dar nu este sinusoidala, sunt mai ieftine )
