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.

 Abstract—This paper discusses surge voltage suppression methods in order to design a large capacity three-phase to single-phase matrix converter which is used in AC-DC converters. In order to reduce the surge voltage, the design criteria based on the flow chart of a laminated bus bar (LBB) for the three-phase to single-phase matrix converter is clarified to achieve the lowest stray inductance. As a result, the maximum stray inductance of the LBB for 200-V, 50-kW is achieved to 59 nH in simulation and 58.3 nH in experiment. Besides, when the surge voltage exceeds the tolerance, a snubber capacitor is used in order to limit the surge voltage. In this paper, the design method of the snubber capacitor is also proposed. Concretely, the relationship among snubber capacitance, surge voltage and turn-on loss is derived. As the result, it is confirmed that the surge voltage becomes 231 V when the output current is 310 A by experiment. Thus, the design method of snubber capacitor to suppress the surge voltage is validated.
