A PWM cycloconverter switches power supplies without interrupting operation if a fault occurs in a power supply. In case of trouble with a 3-phase AC power supply (1), a fault detector circuit (30) produces a signal (120) indicative of trouble, and a power switch (20) selects the output voltage from an uninterruptible power supply (10). A phase detection switch (43) selects the phase information from a phase detector (41) of the uninterruptible power supply. The phase detector (41) continues to detect the phase of the uninterruptible power supply (10) before a fault occurs in the power supply so that the exact phase information on an uninterruptible power supply (10) can be available immediately after a change of phase information from the phase detection switch (43). Therefore, operation will not be interrupted in switching power supplies.

Selon l'invention, un cycloconvertisseur MID commute un circuit d'alimentation électrique sans en interrompre le fonctionnement lorsqu'une panne survient dans un circuit d'alimentation. En cas de problème avec un circuit d'alimentation c.a. triphasé (1), un circuit de détection de panne (30) produit un signal (120) indiquant le problème, et un commutateur électrique (20) prend la tension de sortie d'un circuit d'alimentation ininterruptible (10). Un commutateur de détection de phase (43) prend l'information de phase d'un détecteur de phase (41) du circuit d'alimentation ininterruptible (10). Le détecteur de phase (41) continue de détecter la phase du circuit d'alimentation ininterruptible (10) avant la survenue d'une panne dans le circuit d'alimentation, de sorte que l'information de phase exacte sur un circuit d'alimentation ininterruptible (10) soit immédiatement disponible après un changement de l'information de phase émanant du commutateur de détection de phase (43). Ainsi, l'opération de commutation de l'alimentation électrique n'est pas interrompue.
