Traditionally, power converter design for energy storage systems (BESS) normally focuses on conversion efficiency and total ...

EPC and Analog Devices introduce reference design using a new Analog controller fully optimized to drive EPC GaN FETs. The combination of the new Analog LTC7890 synchronous GaN buck controller with ...

Switching has almost always meant “hard" switching, which is simple but comes with all kinds of electrical and thermal ...

What are GaN HEMTs and why are they important? How GaN devices can handle kilowatt power conversion. Gallium-nitride (GaN) high electron mobility transistors (HEMTs) are a form of field-effect ...

Click modulation is a coding technique that was developed in the mid 80's by Logan (1984) to retrieve information encoded by the zero crossings of certain bipolar signals. Somewhat akin to pulse-width ...

AC/DC power-factor correction (PFC) rectifiers are hugely benefitting from GaN FETs. They have very simple topologies; The inductor is the only magnetic part and this is usually a constant-frequency ...

Sounds that are lower pitched are less studied than other types. Some say it’s a health hazard. Others have doubts. By Lourdes Medrano/Undark Published Apr 17, 2024 8:00 AM EDT This article was ...

Researchers at the Universitat Autònoma de Barcelona (UAB) worked on developing a switch, a crucial component of modern telecommunications that can run at a very high frequency while using less power ...

Researchers at Sichuan University have proposed a four-level modulation strategy for dual three-phase open-winding PMSM drives, offering higher efficiency and lower current harmonic in such ...
