Technology:
Yaskawa Electric successfully reduced the volume of the existing power conditioner to one-25th
without decreasing the output capacity. The new small power conditioner will be
helpful to make an autobody lighter for better mileage should it be mounted on
an e-vehicle. The company used silicon carbide-based power semiconductors that
increase efficiency of power conversion and increased the output per liter.
Silicon carbide operates even at a high temperature, and it is featured by a small
amount of power loss in conversion. The company built a trial product. It has
an output of 45 kW, and its outside dimension is 35.8 cm x 28.2 cm x 2.9 cm.
The company wishes to commercialize the small power conditioner by 2014.
Yaskawa will quintuple the production of power conditioners to satisfy the growing demand after the introduction of the system that lets electric power companies purchase renewable energy. The company will increase the monthly production capacity from 200 units to 1,000 units. Because direct current created by solar batteries need to be converted to alternate current, a highly efficient power conditioner is critical in photovoltaic generation. In addition, a power conditioner adjusts the unstable voltage of electricity created by photovoltaic generation.
