Low voltage direct current

Renewable energy generates direct current (DC) and we use it in our homes to power many of our devices, from LED lights to mobile phones. IEC work ensures DC is generated, transmitted and used safely

Living in a DC world

While most electricity is produced in large power stations and delivered to our homes as alternating current (AC), in reality, we are increasingly living in a DC world. Nowadays, the majority of devices we use in our homes, offices, healthcare facilities, greenhouses or data centres operate on DC power.  
 
 
In developed economies, the use of low voltage direct power (LVDC) will help improve energy efficiency and reduce global carbon footprint. It can power data centres, office buildings or hospitals. In developing countries LVDC provides affordable and sustainable electricity access to people who would otherwise have to wait many years for a connection to the main electricity grid.

 

IEC is leading efforts to make LVDC technology safe for use everywhere where DC power can be used directly without losses in energy conversion. The IEC systems committee SyC LVDC coordinates the work of all relevant IEC Technical Committees involved in this area.

LVDC: electricity for the 21st century

Low voltage direct current (LVDC) is a disruptive technology that fundamentally accelerates energy access and improves energy efficiency. LVDC applications are many and varied, and can be applied in every country in the world.

Electricity access

The applications for LVDC are wide and varied and apply in every country in the world. They range from residential and business buildings, to data centres, hospitals, retail, transportation, lighting, agriculture or fish farming.

LVDC: another way

The applications for LVDC are wide and varied and apply in every country in the world. In fact, it is hard to find an application, where LVDC will not effectively replace AC in delivering electricity more efficiently to more people and businesses.
