IGBTs offer strengths of both MOSFETs & IGBTs
Offering the strengths of both MOSFETs and IGBTs, the BiMOSFET series of Reverse Conducting IGBTs has been released by IXYS. The 3600V devices, which are suitable for high speed, high voltage, and high current power conversion applications feature ‘free’ intrinsic body diodes, and have current ratings from 45 to 125A.
Programmable AC/DC power supplies offer 12VDC, 54VDC
An addition to Murata Power Solutions’ D1U4 series of AC-DC front-end power supplies features a dual I2C interface, controllable bidirectional output isolation. The compact D1U4 measures just 41 x 355.6 x 101.6 mm and allows up to four supplies to be contained on a single 1U-high 19-inch rack-mounting chassis.
Transformers are vacuum impregnated to 0.25µm
A series of transformers, designed for aerospace and military equipment, and satellites and telecomms, has been released by Innovative Power. The High Voltage Transformers, which meet power and reliability requirements in rugged operating environments, operate from 400V to 50kVA.
Power supply fits medical & industrial footprint
Measuring 101.6x152.4x42.4mm (4.00x6.00x1.67"), the GSP500 series of highly efficient 500W AC/DC power supplies has been introduced by XP Power. The single output forced air cooled units require just 12CFM thanks to its high efficiency design and an almost entirely flat efficiency curve over the whole load range.
Battery charger delivers 25ADC charging current at 25°C
Developed for applications which require long autonomy times, Ideal Power announces its 25A output 31FC2512-BHFHigh Current OEM Battery Charger. The Ideal Power IP support engineering team creates bespoke power solutions to meet individual requirements in today's growing high-power battery market.
MOSFET gate drivers improve conversion efficiency
Designed to control the high-current power MOSFETs used in on-board and embedded power supplies and motor drive circuits, a pair of compact 40V, 1A-rated gate drivers have been introduced by Diodes Incorporated. The ZXGD3009E6 and ZXGD3009DY help MOSFETs to be more rapidly and fully switched on and off, minimise switching losses, improve power density and increase overall conversion efficiency.
MOSFETs' low RDS(on) reduces conduction losses
Designed for Li-ion battery protection applications, a broad portfolio of low-voltage MOSFETs has been released by International Rectifier. The MOSFETs, which are available as 20 and 30V devices in N-and P-Channel configurations, feature low RDS(on) to reduce conduction losses. Suitable for battery protection circuits with two cells in series, the devices are designed with a maximum gate drive of 12VGS.
Intermediate bus converter targets ATCA applications
Targeting ATCA (Advanced Telecommunications Computing Architecture) applications, the PKM4613ANH 580W high-power DC/DC Intermediate Bus Converter (IBC) module has been introduced by Ericsson. The Hybrid Regulated Ratio (HRR) topology based device delivers a regulated output voltage that not only complies with standardised system voltages for telecomms applications, but also ATCA input voltage requirements, including a stable voltage supply f...
High-voltage resistor features corona discharge shield
Cressall have designed a resistor to safely withstand the mechanical and thermal stresses of the 48MJ that is applied for 0.25s at the switch-on of HVDC systems using voltage source converter technology.
Power supplies meet global 'on the go' applications
BEC Distribution has added the Stontronics range of Plug & Go (World Traveller) power supplies. The T5574ST is a 12V 3A power supply unit that comes complete with UK, Euro, US and Australian interchangeable AC heads. The power supply unit has a particularly small and compact design of 49 x 84 x 42mm, making it ideally suited to “on the go” applications and worldwide travel use.
