Emerson: AC Power Conditioners and Protection for Retail/C-Store Apps


Libertyville, IL — Emerson Network Power’s ONEAC Total Power Protection Solutions are designed specifically to address the growing power needs of the harsh C-Store environment. The state-of-the-art power con-


ditioning technology is available in the company’s premium product line of power conditioners and power con- ditioned UPS units, along with its communications line protectors. Engineered to meet the special

San Jose, CA — PowerTrench® MOS - FETs from Fairchild Semiconductor reportedly increase system efficiency and power density in synchronous rec- tification applications. This is espe- cially useful for designers who need to improve system efficiency and mini- mize components in applications like high efficiency AC-DC converters. Fairchild Semiconductor has


expanded the PowerTrench® MOS- FET family of 100 and 150V devices to include industrial-type packages,


needs of the retail environment, these units protect incoming power, eliminating harmful disturbances, reducing equipment downtime and service calls. In addition, the compa- ny’s ONEAC ManageUPS® CIO cen- tral monitoring software is designed distributed UPS and critical infra- structure operations. According to the company,

unprotected power entering a retail facility can disrupt, degrade and even damage critical equipment resulting in serious financial losses


and inconvenience to customers. The company provides innova-


tive solutions and expertise in areas including AC and DC power and pre- cision cooling systems, embedded computing and power, integrated racks and enclosures, power switch- ing and controls, infrastructure man- agement, and connectivity. Contact: Emerson Network

New MOSFETs increase rectifier power density.


including the TO-220, D2PAK, TO247, I2PAK, TO220 Full Pack and D2PAK-7L. Part of the mid-voltage power


MOSFET portfolio, these devices are optimized power switches that com- bine a small gate charge (QG), a small reverse recovery charge (Qrr) and a soft reverse recovery body diode, which allows for fast switching for synchronous rectification in AC- DC power supplies. These devices employ a shielded-


gate structure that provides charge balance. By using this technology, the figure of merit (QG x RDS(ON)) is 66 percent lower than previous solutions, providing designers a high efficiency solution for applications including synchronous rectification, micro-solar inverters and offline UPS systems and PDU/BFU in telecom power dis- tribution. A low reverse recovery charge


and the soft reverse recovery body diode reduces voltage spikes or oscil- lation in the system, eliminating the snubber circuit — or replacing a higher voltage rating MOSFET — enhancing efficiency and reducing the design bill of materials.
