Brief
Description
In most buildings, including
our homes, we are surrounded by devices and
equipments that internally operate on DC.
Examples of these devices are PCs, LED lights,
televisions, mobile phones, and other electronic
appliances. Renewable sources like PV systems,
electricity is generated as DC and it is
converted into AC to supply the existing
systems/networks. All these conversions are
associated with power loss. These losses can be
significantly reduced by LVDC home architecture. Advantages of
LVDC home
1. Reduced AC-DC conversion stages
Improved energy savings due to high
efficiency of DC equipments
2. Direct interconnection with
non-conventional resources like solar PV
3. Easily compatible with efficient home
equipments like BLDC fans, LED lights
4. Better power quality (No power factor
and harmonics related issues)
5. Safe and secure voltage level ensures
human safety
Main uses and domain
Domain: Low Voltage Direct Current (LVDC)
distribution system with Renewable
Energy Integration
