The standard UPS technology most widely accepted by the industry as the ideal solution for large installations to date is double conversion and the variations of its configuration. In double conversion mode the UPS provides reliable insulation against power quality problems. It allows control of output voltage and frequency regardless of the voltage and frequency input conditions.
But we must pose the question, is double conversion the only possible solution for resolving these types of disturbances?
Although double conversion technology has proved to be reliable in protecting installations against almost any and every type of disturbance it has one notable drawback — efficiency. In providing such high protection, double conversion UPS constantly work in Maximum Protection mode, causing them to use a large amount of surplus energy.
