Würth Elektronik debuts phototransistor optococouplers
Phototransistor-type optocouplers are available for the first time from Würth Elektronik. The WL-OCPT Series 816 coplanar design optocouplers consist of an infrared LED on the input side and a phototransistor on the output side.
Suppressing acoustic noise in switched-mode power supplies
When sitting in a car, the engine noise we experience is something completely normal. After all, the engine compartment contains a machine with moving parts in it. In fact, manufacturers of cars and other products actually have entire research departments dedicated to tinkering around with (and creating) pleasurable sound experiences. However, as Rolf Horn, Applications Engineer at Digi-Key Electronics explains, it is a different situation with s...
InnoSwitch3 flyback switcher IC for automotive BEV
Power Integrations has announced the production release of the InnoSwitch3-AQ, an AEC-Q100-qualified flyback switcher with integrated 750V MOSFET and secondary-side sensing.
Optical Technology withstands IGBT Destructive Testing - Would alternative Isolators withstand this?
The polyimide film and insulation barrier of Broadcom gate drive optocouplers proves robust even during catastrophic failures like the IGBT destructive tests presented in this paper. Although the gate driver boards were damaged, the gate drive optocouplers were able to pass partial discharge and high voltage tests, providing reinforced insulation, protecting the systems and users.Read more here.
Phototransistor optocoupler saves energy and space
An Automotive Grade phototransistor optocoupler that combines a high current transfer ratio (CTR) range from 50% to 600% with a low forward current of 1mA in the compact SOP-4 mini-flat package has been introduced by Vishay Intertechnology.
Single IC can produce isolated or non-isolated ±12V outputs
Electric vehicles, large-scale battery storage stacks, home automation, industrial, and telecom power all require converting high voltages to ±12V, where dual polarity rails are required for powering amplifiers, sensors, data converters, and industrial process controllers. Zhijun Qian, Senior Engineer and William Xiong, Applications Engineer, at Analog Devices (ADI) investigate.
Highly robust gate drivers ensure system safety
Power Integrations hasannounced the launch of its automotive-qualifiedSID1181KQSCALE-iDriver gate driver for 750V-rated IGBTs. The new part expands the company’s range of auto-qualified driver ICs, following the introduction of the 1,200V SID1182KQ driver IC.Compact, efficient and highly robust, the new driver IC uses Power Integrations’ high speed FluxLink communications technology to ensure system safety even during fault conditions...
Opto-compatible single channel isolated gate driver for IGBTs
The UCC23513 from Texas Instruments is an opto-compatible, single-channel, isolated gate driver for IGBTs, MOSFETs and SiC MOSFETs, with 4.5A source and 5.3A sink peak output current and 5.7KVRMS reinforced isolation rating. The high supply voltage range of 33V allows the use of bipolar supplies to effectively drive IGBTs and SiC power FETs.
