Transformer based UPS VS transformerless UPS
A transformer based ups system provides an isolation mechanism. There are inrush currents from all the mechanical equipment. This is not the place for a traditional computer UPS system. In recent years, the use of Uninterruptible Power Supplies (UPS) has become increasingly common in data centers, hospitals, and other critical facilities. UPS systems are designed to provide backup power to…

STMicroelectronics’ STGAP2HS is a compact, high-voltage gate driver for applications that require up to 6kV galvanic isolation between the gate-driving channel and the low-voltage control and interface circuitry. The 1200V device can sink and source up to 4A output current to simplify the design and enhance the reliability of mid- and high-power convertors, power supplies, and inverters […]
The EVAL-1ED020I12-B2 evaluation board from Infineon Technologies demonstrates functionalities and key features of the single-channel galvanic-isolated gate driver IC 1ED020I12-B2 for 600V / 1200V IGBTs. The main features of the board are galvanic isolation, isolation inside the half bridge by defined creepage, short circuit protection, active miller clamp and under voltage lock-out. Target applications include …
Power Integrations today announced a range of galvanically isolated transformers that provide the correct voltage and power for the company’s SCALE-iDriver™ family of gate drivers. The combination delivers a simple, robust and cost-efficient dc-dc converter solution that does not require additional voltage regulation, reducing system cost and development time. The SIT12xxI transformer and SCALE-iDriver ICs …
X-FAB Silicon Foundries SE announced the full volume production release of its new high-temperature galvanic isolation semiconductor process. This proprietary technology is fully automotive qualified and the company says it offers enhanced reliability compared to options from the competition. Galvanic isolation electrically separates circuits to enhance noise immunity, remove ground loops, and increase common mode …

Lethal LED Lantern Leaks Lotsa ‘Leccy
When you take an item with you on a camping trip and it fails, you are not normally in a position to replace it immediately, thus you have the choice of fixing it there and then, or doing without it. When his LED camping lantern failed, [Mark Smith] was in the lucky position of camping at a friend’s compound equipped with all the tools, so of course he set about fixing it. What he found shocked him metaphorically, but anyone who handles it while it is charging can expect the more literal variation. The lamp was an LED lantern with …read more http://pje.fyi/PXYZw3
For higher protection and superior sensitivity
When looking for a good current sensing IC, what are the specifications that you prioritize? Does it include a fully differential architecture? High Bandwidth? Small footprint? Has back-end amplifier? Then Allegro's ACS726 current sensor IC is all you need. ACS726 is the first current sensor IC to include a fully differential back-end amplifier (BEA). This consists of a precise, low-offset, linear Hall sensor circuit. Through a close proximity of the magnetic field to the Hall transducer, ACS726's accuracy will optimized.
This device has a dimensions 8.66 mm x 5.99 mm x 1.75 mm, so small but does a great job. With its externally adjustable gain, thru the BEA, the IC's sensitivity can be adjusted. Applications like motor control, load detection and management, switched-mode power supplies, and over-current fault protection are the reason why this device was designed.
