Device for supplying power uninterruptedly.

摘要

IN A DEVICE FOR SUPPLY UNINTERRUPTED POWER is provided a first converter (W1) FOR THE TRANSFORMATION OF A TENSION reciprocates in a voltage modulation pulsewidth and a second CONVERTER (W2) FOR CONVERSION OF A DC voltage CONTINUOUS obtained from a battery (33) in a modulation voltage pulse width. OUTPUTS CONVERTERS (W1, W2) are connected TO EACH the primary windings (16, 17, 18) of a transformer (E), the WINDING SECONDARY (20) DRIVING A AC voltage OUTPUT. CONVERTERS (W1, W2) can be activated by IMPULSE SYNCHRONOUS each other.
