Since most of the electricity in the world is generated by the burning of fossil fuels, developing better systems for the more efficient use of electric power will be an essential part of the solution to the global warming crisis. Almost all modern office equipment made in the last ten years has become world wide compatible, but operates with a power factor of only 55% to 65%. This is the typical power factor for virtually all modern switchmode power supplies operating from a single phase AC supply, because
Although rectification and filtering has been the classic and universal method of turning AC into DC, it is a very inefficient and wasteful SUV-like approach to electrical consumption, where only the voltage peaks are used, and the rest of each waveform is wasted. The wasted 35% to 45% goes back into the grid as higher order harmonics of the power line frequency, which do no useful work, and harm the grid and other equipment. Harmonics are an electrical pollution which overheat utility transformers and neut
Coherent Power has developed and patented technology which integrates modern power factor correction techniques with modern switchmode power supplies. In higher power applications, it can be integrated into existing products, or be used as an add-on. For multiple low power devices, such as the typical office full of computers, monitors, printers, scanners, and copiers, etc., an add-on device which can operate from 20 to 60 computer systems has been designed and a demonstration unit constructed. This device
