Rectifier is a rectifying device, in brief it is high frequency switching power supply unit which can convert AC (Alternating Current) to DC (Direct Current). It has 2 main functions: first, make alternating current (AC) into direct current (DC), supply to load or inverter after smoothing; second, to provide charging voltage to battery. Therefore, rectifiers also act as a charger. General usage areas are power plants, conventional power generation, oil & gas industry, water/wastewater industry, nuclear industry, mining industry, power transmission and distribution industries, naval platforms, telecommunication centers, marine and land transport vehicles, hospitals, conventional power generation, military facilities and all kinds of battery charging applications.
Rectifiers are produced with 6 and 12 pulse according to application requirements. The biggest advantage of the 12 pulse rectifier groups is better input power factor than 0.9 and less input current harmonic than 10%. Also 18 and 24 pulse rectifiers can produce regarding to your request.
The AC ripple on the DC output is provided under 1% with the optional L-C filters in the output. In that way, the desigin life of the charged battery group can maximized. Inputs and outputs can be individually control via circuit breakers. In addition, the required data can be provided with dry contacts output.
