DC power is beginning to evolve towards replacing AC as a worldwide standard for electricity delivery infrastructure, in many applications, based on the nine reasons listed below:
1. DC power is significantly
more energy efficient than AC power.
• DC motors and appliances have higher efficiency and power to size characteristics.
• DC-based lighting (LED) is as much as 75% more efficient than incandescent lighting.
• The greater efficiency resulting from recent developments in DC converter technology allows improvements in electricity delivery over long distances.
