Abstract
A novel conversion system for a UPS (uninterruptible power supply) using a high-frequency link is described. The UPS consists of a high-frequency inverter and transformer and a cycloconverter. The cycloconverter can be operated by both source commutation and self-commutation (by turning off the switching devices). A choice is made between the two commutation methods, depending on switching device losses during commutation and the internal voltage drop caused by commutating reactance. A compact and efficient UPS can be realized with this conversion system.<>Keywords
