Toshiba Carrier Corporation (TCC) announced that its energy-efficient inverter technology was recently recognized for innovative technical development at the 79th Academic Promotion Awards of the Institute of Electrical Engineers of Japan (IEEJ). The award ceremony was held in Tokyo in May.
The awards honor engineers who make notable achievements in the field of electrical science and technologies by proposing and/or demonstrating a new concept, idea, material, device, system, method or by developing or improving a new product or equipment. TCC was recognized for the development and practical application of its dual-inverter system for open-end-winging motor drive in air conditioning units.
Today, secular trends such as decarbonization and energy conservation are driving demands for highly efficient HVAC products. To achieve both high efficiency at partial load and high maximum capacity, high counts in motor winding turns and high DC voltage for reducing circuit current has been commonly used, but increased circuit current necessary for increased maximum capacity has resulted in larger components and higher costs. The award-winning dual-inverter system technology enables a compact and low-cost system that delivers high-efficiency operation.
“The innovative technology was developed based on our key engineering strengths - inverters and compressors,” said Tsutomu Masamoto, leading Technology and Innovation in Japan, Global Comfort Solutions, Carrier. “We will continue to focus on developing new technologies that support customers’ decarbonization journey.”
