Diamond Electric Develops Three-port Power Conversion Technology

Abstract PV solar energy is becoming increasingly more prevalent in electricity generation for residential and commercial buildings. Existing DC power converters typically have low power conversion efficiency at light and heavy load conditions.

Much research has been done on efficiency improvement of DC converters, but material, technology, and manufacturing processes all impose limitations on efficiency gain. This paper addresses the efficiency improvement of a DC microgrid with a power array conversion PAC for a commercial building application. The PAC configuration utilizes an array with three equal and parallel converters instead of a single larger converter to cover a wide range of load conditions.

As power conversion is a large part of power loss in DC microgrids, especially for step-up conversion, the proposed PAC is developed to improve the conversion efficiency.

Analysis results show that the proposed DC microgrid can improve the conversion efficiency up to A review of the converter hardware costs indicates that the PAC approach offers savings on the initial purchase of a converter. Furthermore, an array with three converters can improve the system reliability since it offers a level of redundancy where one or two converters can continue to operate, albeit at a lower power output, when other converters in the array are out of service.

Expert assessments on the future of direct current in buildings

In environment-friendly equipment, multiple voltage levels may coexist within equipment for reasons such as the characters of devices used, the utilization of existing models, and safety. Conventionally, dedicated power converters for every voltage level were used, which resulted in the large size and cost of a final product or system. In response, the three-port power conversion technology developed by Diamond Electric enables a single power converter to perform power conversion across three different voltage levels. The technology of integrating multiple power converters into one is expected to reduce the size and cost of a final product or system. This feature makes the technology highly compatible with environment-friendly equipment such as a battery system that supports both charging and discharging operations and a utility interactive system that supports both the selling and buying of electricity.

Hybrid Inverter. Hybrid technology: Most inverters only use one source of energy to power loads, either from incoming AC power - shore or AC generator - or from the batteries. We stock a wide range of solar power inverters, including Hybrid Inverters, to complete your PV project. In residential solar applications, a hybrid inverter combines the work of a grid-tied inverter and battery inverter. With the Darfon HB51 hybrid transformerless inverter, energy storage can be added to homes and small commercial buildings, with or without a PV system. This series of inverters can be widely used in various places such as household energy storage, industrial and commercial energy storage, and small micro-network system. Because of this compatibility issue, buying a hybrid inverter and saying "I can just add any battery I want later" is not correct, as changing technology might haunt you.

Commercial buildings include a variety of building types —offices, hospitals, schools, police stations, places of worship, warehouses, hotels, and shopping malls. Electricity and natural gas are the most common energy sources used in commercial buildings. Most individual commercial buildings have their own heating and cooling systems. However, there are district energy systems that supply heating and cooling to groups of commercial buildings. When many buildings are close together, such as on a college campus or in a city, having a central heating and cooling plant that distributes steam, hot water, or chilled water to multiple buildings is sometimes more efficient. District energy systems may also produce electricity along with heating and cooling energy. District energy systems generally use fossil fuels coal, natural gas, or fuel oil , although some use renewable sources of energy biomass, geothermal, solar, and wind energy. Click to enlarge.

Power Quality and Distribution

In today's increasingly electrified world, power conversion--the process of converting electricity between different currents, voltage levels, and frequencies--forms a vital link between the electronic devices we use every day and the sources of power required to run them. The projects that make up ARPA-E's ADEPT program, short for "Agile Delivery of Electrical Power Technology," are paving the way for more energy efficient power conversion and advancing the basic building blocks of power conversion: circuits, transistors, inductors, transformers, and capacitors. Fusion energy holds the promise of cheap, clean power production, but up to now scientists have been unable to successfully harness fusion as a power source due to complex scientific and technological challenges and the high cost of research. ARPA-E's ALPHA program seeks to create and demonstrate tools to aid in the development of new, lower-cost pathways to fusion power and to enable more rapid progress in fusion research and development. Energy storage can significantly improve U. While rapid progress is being made in new battery materials and storage technologies, few innovations have emerged in the management of advanced battery systems.

Hybrid Inverter

An electric power system is a network of electrical components deployed to supply, transfer, and use electric power. An example of an electric power system is the grid that provides power to an extended area. An electrical grid power system can be broadly divided into the generators that supply the power, the transmission system that carries the power from the generating centres to the load centres, and the distribution system that feeds the power to nearby homes and industries. Smaller power systems are also found in industry, hospitals, commercial buildings and homes. The majority of these systems rely upon three-phase AC power —the standard for large-scale power transmission and distribution across the modern world. Specialised power systems that do not always rely upon three-phase AC power are found in aircraft, electric rail systems, ocean liners and automobiles. In , two electricians built the world's first power system at Godalming in England. It was powered by two waterwheels and produced an alternating current that in turn supplied seven Siemens arc lamps at volts and 34 incandescent lamps at 40 volts. The Pearl Street Station initially powered around 3, lamps for 59 customers.

How disruptive technologies are changing the power sector

The electricity grid is a complex and incredibly important system, and one of the most impressive engineering feats of the modern era. It transmits power generated at a variety of facilities and distributes it to end users, often over long distances. It provides electricity to buildings, industrial facilities, schools, and homes.

Protect against voltage surges and sags, power interruptions, electrical noise and other power quality problems. Power conversion choices made upstream can impact the type of power protection required downstream. Our products and expertise can save you time, money and space with combined power protection and conversion solutions that are right for your facility.
