BACKGROUND AND PRIOR ART:
[002] For increasingly complex electronic and computer devices, power source devices become increasingly important. Historically, power backup systems have relied on traditional analog control techniques, which are limiting in the level of control that can be provided and in the aspects of the backup supply's operation that can be controlled. Conventional inverter circuits can be divided into half-bridge-type, full-bridge-type and push-pull-type according to different types of circuits. An inverter circuit is a circuit for converting DC power into AC power.

[019] Reference may be made to an article by “Rossetto, L.; Malesani, L.; Tenti, P; Buso, S; Pollmann, A, Oct 1995, Industry Applications Conference”. The present article explains a fully digital control technique for voltage-fed three-phase inverters to be used in uninterruptible power supplies.

After a short description of the system, attention is focused on VECON'S performances and implemented control algorithm. Even if no transformer is used in the power converter, the line-to-neutral voltages are independently controlled thus allowing supply of single-phase or unbalanced loads.
