Control up to 32 thyristor modules via RS485
TDK has introduced the BR7000-I-TH and BR7000-I-TH/S485 power factor controllers. The BR7000-I-TH offers 12 relay outputs for capacitor contactors and 12 transistor outputs for thyristor modules and the BR7000-I-TH/S485 features an additional RS485 bus interface that allows up to another 32 EPCOS TSM-LC-S thyristor modules to be controlled. This bus interface also enables bidirectional communication with the thyristor modules.
40V Trench-MOSFETs deliver 0.7mΩ typical RDS(ON)
Based on the company’s next generation U-MOS IX-H semiconductor process, Toshiba has introduced its latest family of low-voltage, ultra-efficiency Trench-MOSFETs. According to the manufacturer, these MOSFETs deliver industry leading RDS(ON)*QOSS (on resistance to output charge product) figure of merit for this class of devices.
SiC MOSFETs for high-voltage industrial applications
Designed for high-power industrial applications where efficiency is critical, Microsemi has introduced its silicon carbide (SiC) MOSFET product family with 1200V solutions. Typical applications for the APT40SM120B, APT40SM120J, APT50SM120B and APT50SM120J include solutions for solar inverters, electric vehicles, welding and medical devices.
Monitors significantly improve battery pack safety
Efficiently protecting and controlling 3-15 cell batteries when charging or operating in harsh environment conditions, Texas Instruments has introduced the bq76920, bq76930 and bq76940 circuits. TI claims that these are the first scalable, multi-cell battery monitors that significantly improve battery pack safety and reduce design time of 12-48V lithium-ion and lithium-iron phosphate batteries used in e-bikes, power tools and energy storage syste...
Gate driver for demanding industrial applications
Developed for high-end systems in the industrial sector, Infineon Technologies has introduced the 1EDS-SRC EiceDRIVER Safe driver. The component features the first Slew Rate Control (“SRC”) adjustable in real-time at the IGBT and the secure electric isolation of complies with the strict specifications of VDE 0884-10 and has specially developed short-circuit protection functions.
Power supplies for ITE, industrial and consumer applications
Operating from inputs of 30-85W, the VOF series of compact, open frame AC-DC power supplies has been announced by CUI. The single-output supplies deliver higher efficiencies, improved no-load performances, and a boost in power versus the previous generation, making them suited for use in ITE, industrial, and consumer electronics applications.
Device delivers 100W output power in 2.9cm2 footprint
The ISL8240M power module has been launched by Intersil, with the company claiming the device sets a new standard for efficiency and power density in infrastructure and embedded computing applications. The dual 20A/single 40A step-down power module delivers up to 100W of output power in a 2.9cm2 footprint, whilst also providing more than 90% power efficiency.
Integrated power modules offered in alternative DIP packaging
Surface mount devices are not the answer for every customer and International Rectifier recognised this issue and launched the µIPM-DIP family of highly integrated, compact Integrated Power Modules (IPM). The devices were originally launched, and are still available in a compact, surface mount package.
PFC & DC/DC converter improve power conversion efficiency
Two devices, designed to improve power conversion efficiency in large data centre environments, have been introduced by Murata. The first device is a 5kW PFC converter with a 3-phase AC input, whilst the other is a matching high input voltage 1,200 Watt DC-DC converter.
Module delivers 600W over the 42V to 75V range
The PKM4613NH is the third version of Ericsson's quarter-brick power module based on the company’s Hybrid Regulated Ratio (HRR) topology. Designed to power applications that require stable voltage, the device offers available power up to 600W across a wide input voltage range of 36V to 75V and an operating temperature range of –30°C to +90°C.
