We are surrounded by devices and equipment that runs on Direct Current (DC). We plug these devices into an Alternating Current (AC) outlet and then convert AC to DC to operate them. The same goes for sites like telecom that draws AC power from the main source and passes it through a rectifier. AC is being converted to DC to operate active equipment like generators and batteries on the site. Typically, a rectifier has a peak efficiency of 86 to 92 percent as some energy is lost during the conversion process. Anything that falls below this range is considered inefficient and investigation should be done to regain the optimum efficiency. Why are we converting AC to DC? If the AD to DC conversion process causes a reduction in power efficiency, why are we still doing it?
- For power transmission from the main source to an independent site.
- For power storage in batteries.
- To power AC mains electricity.
