Efficient Hybrid Home System
For a long time, conventional energy has been used as an energy source, which includes combustion, producing carbon footprints in large amounts. This ultimately has adverse effects on our environment, leading to global warming and a shortage of conventional energy resources. Renewable energy sources such as solar PVs are an excellent alternative. Additionally, most of the home appliances are DC-internally, i.e., they involve the conversion of AC-to-DC for their internal function. About 15-20% of power is lost in the conversion stages.
To overcome this problem, we had designed an “Efficient Hybrid Home System,” which uses both conventional (AC-utility) and nonconventional energy (PV) as a power source for the home. The PVs are connected to the DC-bus through a Buck-Boost converter to provide a constant voltage. The DC loads are directly connected to the DC-bus without involving conversion stages, resulting in improved efficiency. A bidirectional converter will act as a bridge between AC and DC bus. If AC utility is not present, power to the AC loads connected to the AC-bus will be provided by the bidirectional converter. Similarly, if there is no power at DC-bus this converter will act as a rectifier to feed DC loads connected to the DC-bus. Moreover, a backup battery system ensures continuous power to the home, and a charge controller will control the battery from overcharging and discharging.
