Uninterruptible Power Supply (UPS) Solution

Uninterruptible power supplies (UPSs) are necessary for the continued operation of equipment in the event of a power failure. By supplying power that was normally charged from commercial power to the battery, the equipment can be safely shut down, backed up, and protected when power failure happens by typhoons and lightning strikes for example. Power supply failures cause equipment failure, data loss, file collapse, etc., and the restoration of these system failures requires enormous time and expense. In addition, network system shutdowns can lead to not only physical damage, but also losing of business opportunities and credibility. UPS are indispensable to prevent such situations. In recent years, prices are cheper, and users who record video on high-capacity HDDs at all times, players of online games, and individual online traders are becoming increasingly familiar. High-efficiency performance is strongly required for large-capacity types, while small-and medium-capacity types also require performance such as compactness and light weight. Toshiba's MOSFET having new process technology with a high heat dissipation package, contributes to the realization of a highly efficient power supply, and offering performances suitable for power supply circuitry and output stages of equipment. To maintain stable operation in harsh environments, Toshiba's photocouplers can be used to solve problems.

• MOSFETs’ improvement of power utilization efficiency by reducing on-resistance
• MOSFETs’ high heat dissipation package for reduction of heat generation
• Optical coupling provides high isolation strength and improves signal line operational stability
• Compliance with safety standards (UL, cUL, etc.) (photocouplers)
• Useful application notes, reference designs, and other documents on the web save design cycle time
