Active and passive filtering techniques for harmonic mitigation
The rise of non-linear loads in industrial environments over the last two decades has resulted in the growing problem of harmonic currents and utility-level voltage distortion. Facing a lack of awareness, the industry has struggled to implement effective mitigation techniques. Here, John Mitchell, business development manager of CP Automation explores active and passive filtering.
DC/DC step-down power module delivers 6A performance
A5.5V step-down power module that delivers a continuous 6A output current with up to 95% efficiency has been introduced by Texas Instruments.The TPSM82480DC/DC module integrates power Metal-Oxide Semiconductor Field-Effect Transistors (MOSFETs) and shielded inductors into a tiny, low profile footprint for space- and height-constrained applications such as point-of-load telecommunications, networking, and test and measurement power supplies.
Robust clip-attach package design supports mechanical durability
Littelfuse hasupgraded its switching thyristor line with the introduction of the SJ Series High Temperature SCR (Silicon-Controlled Rectifier) Switching Thyristors. This new series offers circuit designers blocking voltages (VDRM) up to 600V and current ratings from 4-40A to support a wide range of applications. By offering designers a wider operating margin than earlier SCRs, they make it possible to tolerate insufficient cooling and higher inru...
Converters are compact for power conversion in chipsets and FPGAs
Two converters are the first in a family of I2C controllable EZBuck regulators, announced by Alpha and Omega Semiconductor. The 4.0A AOZ2231CQI-01 and the 8.0A AOZ2233CQI-02 provide a compact, efficient power converter solution for next-generation chipsets and FPGAs used in high-end TVs, set-top boxes, data storage systems, servers and other embedded systems, says the company.
TVS diode protection for VFDs/IGBT inverters
In virtually all industrial control systems, variable frequency drives (VFDs)/ inverters are commonly installed at the front end of motors in order to regulate speed and save energy. Based on differing input voltage requirements, inverters are often categorised as low voltage (110, 220 and 380V), medium voltage (690, 1140 and 2300V), or high voltage (3, 3.3, 6, 6.6 and 10kV).
A guide to power factor correction
BEAMA has announced that it has published its 'Guide to Power Factor Correction'. This paper has been written with the member of BEAMA's Capacitor's Group, experts in the field of power factor correction.
Step-down regulator operates in noisy environments
Able to operate in factory automation, industrial robotics, communication infrastructure and avionics systems, the LTM4653 is a 58Vin step-down µModule regulator from Analog Devices.
Step down converter provides electromagnetic compatibility
With the MagI³C-VDMM (Variable Step Down MicroModule), Würth Elektronik eiSos expands its product series of power modules with high power density, very few external components and electromagnetic compatibility. The step down converter with variable output voltage is a particularly compact solution in a LGA-6EP package (dimensions 3.2x2.5x1.6mm).
