Because today’s battery management systems (BMS) are wired, the common source of cable failures – wire harnesses and connectors – becomes a warranty and functional safety issue. With the launch of a wireless BMS that features the first independently assessed functional safety concept, Texas Instruments hopes to revolutionize electric vehicle (EV) BMS. By removing the […]
Power Electronic Tips
Reference design lets secondary MCU control primary power
In modern offline AC-DC power solutions, programmability and adaptive control offer the flexibility and intelligence needed by smart home devices to better interface with their power systems. In these systems, a secondary side microcontroller (MCU) is typically not capable of starting a system without the use of a separate bias power supply. A new reference […]
High-temperature snubberless triacs reduce heat sink needs
STMicroelectronics’ 800V 8H Triacs operate at full rated current up to the maximum junction temperature of 150°C, allowing heatsinks in drives for AC loads to be up to 50% smaller to combine compact dimensions with high reliability. Suited to industrial, personal care, smart-home, and smart-building applications, the new Triacs leverage ST’s latest Snubberless high-temperature technology […]
Single IC integrates power, voltage, and current monitoring, reinforced isolation
Allegro MicroSystems announced the launch of the ACS37800, a Hall-effect power monitoring IC for single-phase AC and DC solutions in a small PCB footprint. Another industry-first innovation, Allegro’s ACS37800 is an integrated power monitoring chip that allows simultaneous measurement of power, voltage, and current for AC and DC signals with an isolation rating of up […]
The basics of AC-line isolation for safety, Part 2: The solution
Isolation from the AC line is essential for user safety in many situations and can be implemented using a special isolation transformer as well as other means. Part 1 of this FAQ looked at the multiple-fault and failure scenario that can put users at risk from AC-line connected products, including appliances, instruments, or medical devices. […]
The basics of AC-line isolation for safety, Part 1: The challenge
Isolation from the AC line is essential for user safety in many situations and can be implemented using a special isolation transformer as well as other means. “Isolation” is one of those terms which gets tossed around and is often cited as an almost universal, all-purpose cure for various ongoing or possible circuit and system […]
The effect of DC bias on MLCC class 2 capacitors
Not all capacitors are created equal. Some are polarized, some are ultra-stable, and others have low dielectric absorption or high volumetric efficiency—all depending on the materials and other physical characteristics in the technologies used in manufacturing. Multiayer ceramic capacitors (MLCC) are divided into types or classes, based on the materials used for the dielectric. These […]
Power system design considerations for wireless IoT nodes and wearables – Virtual Roundtable (part 2)
The second part of EEWorld’s two-part “virtual roundtable” discussion on power system design considerations for wireless IoT nodes and wearables focuses on the use of switching regulators and the associated technical challenges. Our panelists are: Florian Feckl (FF), Systems Engineer and Product Definer for Low Power Buck Converter, Texas Instruments, and Kyle Van Renterghem, (KVR) […]
Power system design considerations for wireless IoT nodes and wearables – Virtual Roundtable (part 1)
The first part of EEWorld’s two-part “virtual roundtable” discussion on power system design considerations for wireless IoT nodes and wearables focuses on the use of low dropout regulators (LDOs). Our panelists are Kyle Van Renterghem, (KVR) Marketing & Applications Manager, Low Input Voltage LDOs, Texas Instruments, and Julian Hagedorn (JH), Systems Engineer, Texas Instruments. JS: […]
Liquid cooling for high-performance thermal management
Liquid cooling comes in two forms, cold-plate based systems, and immersion cooling systems. Cold plate liquid cooling is found in various high-performance applications, including energy storage, transportation, electric vehicles, photonics, LEDs, military and industrial power supply cooling, even in some over-clocked desktop computers. The use of immersion cooling is more limited, and it can be […]
