Toshiba International Corporation (TIC) has introduced the G2020 Series, its latest three-phase uninterruptible power system (UPS), in which silicon carbide (SiC) power modules in a three-level design enable 98%-efficient power protection with 50% load while operating in double-conversion mode.
The firm says that combining the latest in semiconductor technology with innovative circuit topology and high-performance full digital control ensures the highest level of reliable power quality to meet the demanding needs of the data-center industry. With 98.2% efficiency (said to be the highest in the industry for double-conversion UPS), the G2020 produces less heat, noise and interference, lowers cooling costs and saves energy compared with the conventional UPS, it is claimed, and presents a solution for mission-critical infrastructure.
Available in 500 and 750kVA versions, the G2020 UPS provides a solution for demanding data-center applications that require small footprint, high efficiency, and clean uninterruptible power, says Greg Mack, VP & general manager of the TIC Power Electronics Division. "The G2020, with full digital control, instantaneous waveform control and fast-response current control ensures the highest power quality for all UPS users," he adds.
For redundant high-reliability UPS applications, the G2020 has a footprint 17% smaller than its G9000 predecessor and up to 57% smaller than competing models, claims Jesus Penalver, product manager for the TIC Power Electronics Division. "The future of power electronics is SiC power switching technology, with >33% higher junction temperature, higher switching speed, and extremely low switching losses."
