An uninterruptible ac power supply permits parallel operation between a commercial ac line and an inverter unit, greatly simplifies the monitoring of the commercial ac line and minimizes the transient of output voltage during the switching of mode. The uninterruptible ac power supply is comprised of an iron core divided with magnetic shunts into three sections and has an output winding, a winding for a commercial ac line and a winding for an inverter unit, one each wound on the aforementioned three sections of the iron core, the said three windings so disposed that the output winding is wound on one terminal section and the windings for the commercial ac line and the inverter unit are wound on the remaining two sections.
