“…Even though the 3LTI is generally evaluated and investigated to apply in low-voltage industrial systems [16,17], it has difficulties to apply in low-voltage and low-power home appliances such as refrigerators and air conditioners because the increased efficiency is not sufficient due to its complexity and cost problem. More accurately, since the utilization rate of switches is varied according to the modulation index (MI), the 3LTI has together higher and lower efficiency points.…”

-This paper proposes a maximum efficiency operation strategy for three-level T-type inverter in entire operation areas. The three-level T-type inverter has higher and lower efficiency areas compared with two-level inverter. The proposed strategy aims to operate in the maximum efficiency point for the low-voltage and low-power home appliances. The three-level T-type inverter is analyzed in detail, and the two operation mode selection strategy is developed. The proposed algorithm is verified by theoretical analysis and experimental results.

Solar power is not the only attractive energy, but a wind turbine generator is also an attractive energy option from the point of view of reducing double carbon oxide emission. However, to connect the wind turbine generator system to the grid, the independent power producer (IPP) must compensate the power disturbance caused by the wind turbine. Thus, it is necessary to install a power conditioner for stabilizing power disturbance. In this study, the authors have developed a new power conditioner using batteries. The control technique, specifications, circuit configuration, and prototype test results are described.

In Japan, Feed in Tariff has started since July in 2012. Moreover only solar power is not attractive energy, a wind turbine generator is attractive energy from the point of view to reduce double carbon oxide emission. However, to connect the wind turbine generator system to the grid, the independent power producer (IPP) must compensate the power disturbance caused of the wind turbine. Thus, a power conditioner for stabilizing power disturbance is necessary. The authors have developed a new power conditioner using batteries in this paper. The control technique, specifications, circuit configuration and prototype test results are described.
