Uninterruptible Power Supplies and Active Filters
As Industry power demands become increasingly sensitive, power quality distortion becomes a critical issue. The recent increase in nonlinear loads drawing noninusoidal currents has seen the introduction of various tools to manage the clean delivery of power. Power demands of medical facilities, data storage and information systems, emergency equipment, and so forth, require uninterrupted, high quality power. Uninterruptible power supplies (UPS) and active filters provide this delivery. The first to treat these power management tools together in a comprehensive discussion, this book compares the similarities of UPS, active filters, and unified power quality conditioners. It features a description of low-cost and reduced-parts configurations presented for the first time in any publication. These configurations are vital as industries seek to reduce the cost of power management in their companies. As this field of power management continues to grow, industry and academia will come to rely upon the comprehensive treatment found within this book.
