Novel DC Power Feed Inverter-Less On / Off Line UPS for All Electronic Home / Industrial Equipment

Dr. P. S. Kannan [2]


Abstract: The very important technology discovered by the author in the year 2009 is reported first in this paper. The technology is most of all the electronic equipment today used in homes and industries can be operated directly with DC 230 volts supply instead of AC 230 volts normal traditional supply. This dual source operation of the equipment is not known to the public, professors, teachers, students, engineers, researchers and technicians so far, since the manufacturers labeled only AC is the source for operation. They may not also aware about the operation of the equipment by 230 volts DC source (HVDC). The technical reason for the possibility of dual source operation is due to the Switched Mode Power Supply (SMPS) used in the equipment. Based on the discovery, the work presented a novel inverter less, on/offline DC power feed Uninterrupted Power Supply (UPS) system suitable for homes, computers/data centers and industries. The UPS feeds power to the loads when the main supply failure. DC micro grid concept is applied for fabricating the UPS. The cost of fabrication, installation and maintenance is less. Easy to replace the required defective components since all are available in the nearby electronic/electrical shops. The reliability, quality of the system is well improved in comparison with existing inverter UPS system. Electrical energy is also saved Hence the manufactures of the equipment must demonstrate their social responsibility by labeling the dual source operation on the equipment for the awareness of the society. This will lead in implementing the proposed innovated HVDC micro grid UPS technology universally which saves lot of electrical energy. Already a trend is going on in bringing the technology of HVDC power feeds to international standardization. Therefore, the technology has to be included in the curriculum of all science and technical universities worldwide for further developments in the field of power engineering.
