This paper suggests another candidate the Voltage Balancing Inverter for UPS. Recently A commercial power interruptions and voltage variations of sensitive high-tech equipment for industrial, medical equipment, computers, finance, office equipment, such as the use of high use of digital information processing equipment with high reliability while increasing the uninterruptible power system to the growing reality. In this paper, we propose an inverter circuit forming the voltage balance itself without a separate control element. The proposed circuit is to carry the charge of the voltage relative to the high voltage side of the capacitor using the charge moving toward the low voltage and is naturally to balance. The proposed circuit is not required voltage balance controller can be used as a single controller. Even though the number of switches are more than conventional half-bridge inverter structure that can use a rated voltage of the high-speed switch to a lower half of the rated voltage of the conventional circuit.
The validity of proposed system could be verified by simulations, circuit fabrication and experiments.
