In the life test of online uninterruptible power supply (UPS) systems, with heater used as a load, much energy will be wasted in the form of heat. To save energy and decrease the test cost of UPS, an energy feedback method is proposed. Using the utility system instead of the heater load and the principle of parallel operation of transmission, the energy that will be dissipated is turned back to the utility systems. From the experimental results, the energy savings is approximately 82% in life test.
