This new approach has the potential to broaden adoption of PV technology in both the developed world on-grid and the developing world off-grid or unreliable grid. The most complete experimental results are available for the DAB converter. The fundamental approach is sound.

A power factor correction PFC converter draws high-quality power from the grid, and an inverter converts the high-voltage dc power into V ac for conventional ac loads. Further testing is required to validate the efficiency gain. AC terminals, grid side input current and inverter output voltage, for full system simulation.

Examples include cell phone chargers, LED lighting, and computers. Conclusions drawn by the principal investigators have not been reviewed by the Agency. At this time, all elements of the power converter have been simulated, both independently and together.

Top of Page The perspectives, information and conclusions conveyed in research project abstracts, progress reports, final reports, journal abstracts and journal publications convey the viewpoints of the principal investigator and may not represent the views and policies of ORD and EPA.

With a functioning system, efficiency will be evaluated and improvements will be implemented. Short-term tasks for Phase I include building and testing the remaining subsystems, integrating the complete system, and testing the system with a PV panel. With the proposed converter, both dc and ac loads are supplied by either PV power, when available, or the grid, otherwise.

The objective of this project is to develop a power conversion system suitable for supplying power to both ac and dc loads simultaneously from both ac sources, such as the power grid, and dc sources, such as a photovoltaic PV panel.

However, all subsystems interact effectively and support a diversity of loads and sources. Bidirectional flow allows dc loads to be powered from the grid or ac loads to be powered from the PV panel, depending on solar conditions and load levels.

Modern residences contain a diversity of load types. This will increase system efficiency. August 15, through August 14, Project Amount: The primary objective of the DAB is to regulate the low-voltage dc bus 24 V. A conventional power conversion system converts the PV output to ac for grid intertie e.

Some subsystems have been experimentally verified. System electrical architecture, in block-diagram form.

Conventional ac loads include incandescent and fluorescent lighting, appliances that use motors refrigerators, washing machines, HVAC, etc.build a DC power supply to “take out” one polarity from the AC portion and after it was smoothened we used a zener diode clipper to reduce the ripple effect. The ripple effect can be considered a con in DC Power supplies because it introduces noise to other components that need to have.

Objectives To design a volt DC power supply with a maximum output current of mA. To reduce the ripple factor to a value less than %.
