Реферат: A power supply apparatus, such as an on-line UPS, includes an AC/DC converter circuit having an input configured to be coupled to an AC source, a DC/AC converter circuit having an input coupled to an output of the AC/DC converter circuit by a DC link, and a bypass circuit operative to couple and decouple the output of the DC/AC converter circuit to and from the input of the AC/DC converter circuit. Power is transferred from the output of DC/AC converter circuit via the bypass circuit to conduct a test of the apparatus, such as a factory or field load test. For example, power may be circulated around a loop including the AC/DC converter circuit, the DC/AC converter circuit and the bypass circuit to conduct the test in order to test these components under load. A status of such components may be determined responsive to the test. In further embodiments, such components may be calibrated responsive to the test.
