Abstract

An uninterruptible power supply system (100) for use in an electric power circuit includes a three- phase pulse width modulation rectifier portion (102) for converting an alternating current from the electric power circuit to a direct current, a rechargeable battery unit (104) capable of storing and discharging electric energy, a bidirectional battery charger and discharger circuit portion (106) connected to the three-phase pulse width modulation rectifier portion (102) and the rechargeable battery unit (104) and a three-phase inverter portion (108) connected to the bidirectional battery charger and discharger circuit portion (106) for converting a direct current from the rechargeable battery unit (104) to an alternating current of desired parameter values. The uninterruptible power supply system is configured to automatically switch between a grid mode of operation and a battery mode of operation, delivering a steady electric energy to a load circuit.
