Since the 1990s, the world has been working together to save energy to protect the global environment.
Japan has been actively engaged in energy-saving activities, such as introducing the Top Runner Program in June 1999. Consequently, Japan now leads the world in energy conservation technology.
To meet the Top Runner targets, Japanese manufacturers are required to greatly improve energy efficiency of all their home electrical appliances.
Since air conditioners, in particular, consume a lot of power when they operate, much effort has been devoted to reducing their power consumption.
Use of a DC motor for outdoor compressors has been the norm for years in Japan, but overseas, the migration from induction motors to synchronous motors began in earnest only a few years ago. The purpose of using synchronous motors is to enable intricate inverter control over the compressor behavior in order to reduce power consumption, acoustic noise and vibration.
Ever since the Top Runner targets were set for home appliances, Toshiba has endeavored to provide semiconductor devices to address the needs of home appliance manufacturers.
In line with its commitment to delivering optimal solutions, Toshiba now offers all kinds of semiconductor devices for motor applications—motor control MCUs, motor driver ICs and intelligent power devices (IPDs)—the first company in the industry to do so.
Since Toshiba offers a complete portfolio of semiconductor devices for motor applications, our application engineers can quickly identify market trends and customer needs. We have a system in place to share information among all engineers. Toshiba offers optimal total solutions by combining MCUs, motor driver ICs and IPDs in a flexible manner and develops new devices and systems that will address future needs.
Total solutions are available not only in Japan but also in fast-growing China and Southeast Asian countries.
Toshiba will continue to expand its semiconductor portfolio for motor applications and actively offer solutions to meet customer needs.
