Power amplifiers that oscillate—deliberately. Part 1: A simple start.
Editor’s Note: This DI is a two-part series. In Part 1, Nick Cornford deliberately oscillates the TDA7052A audio power amplifier to produce a siren-like sound and, given the device’s distortion characteristics, a functional Wien bridge oscillator. In Part 2, Cornford minimizes this distortion and adds amplitude control to the circuit. When audio power amplifiers oscillate,…
Automatic Evening Light With Cut-Off Timer
Designing a circuit to switch on a light at dusk and off at dawn is straightforward, and many such designs have been featured in EFY. However, lights controlled this way remain on all night, resulting in wasted electricity and reduced lamp lifespan. In most homes and business premises, outdoor lights are turned on at dusk…
Master Embedded Systems Skills
In today’s fast-paced technological landscape, Embedded Systems skills are more valuable than ever. As industries across the globe continue to integrate advanced technologies into their operations, the demand for professionals with expertise in embedded systems is skyrocketing. From healthcare devices and automotive systems to smart home technology and industrial automation, the applications of embedded systems…
Designing power supplies for industrial functional safety, Part 1
A power supply unit is one of the most crucial components in an electronics system, as its operation can affect the entire system’s functionality. In the context of industrial functional safety, as in IEC 61508, power supplies are considered elements and supporting services to electrical/electronic/programmable electronic (E/E/PE) safety-related systems (SRS) as well as other subsystems….
Accelerating silicon carbide (SiC) manufacturing with big data platforms
For decades, we heard silicon was the only answer. However, while the world’s largest fabs were busy taping out silicon, the communities of engineers and scientists working on non-silicon technologies continued pushing forward. Compound semiconductors—semiconductors made from two or more periodic table elements—include indium phosphide (InP), silicon nitride (SiN), gallium arsenide (GaAs), germanium (Ge), indium…
Exploring Analog And Digital Modulation Techniques Through Labview Simulation
– Advertisement – Communication systems form the backbone of modern technology, enabling the transfer of information across various platforms. At the heart of these systems lies modulation, a technique used to encode information onto carrier waves. Modulation is crucial for efficient signal transmission over long distances and across different mediums. There are two primary types…
Microsoft Build 2025: Arm (and AI, of course) thrive
Last week was a biggie for those of you into tech conferences. First and foremost, of course, there was the 2025 iteration of the Silicon Valley-located Embedded Vision Summit, for which I have both personal interest and professional association. In parallel (and in Taiwan), a “little” computer conference called Computex was going on. And from…
“It Is Similar To The Small Amount You Would Get From A Quick Walk In The Midday Sun”- Girish K Chawla, Signify
– Advertisement – Can gentle UVB light naturally boost vitamin D levels indoors? That too similar to natural sunlight, without the risk of harsh UV rays overexposure? Girish K Chawla from Signify tells EFY’s Nidhi Agarwal how. Girish K Chawla, Head of Professional Business – Signify, Greater India Q. Why do we need a ultraviolet…
Benefits of Mock Interviews
For job seekers, navigating the labor market can be a difficult process. Being well-prepared for an interview is crucial given the intense competition and ongoing pressure to perform well. Taking part in mock interviews is one of the best ways to prepare for a job interview. Candidates can enhance their communication skills, gain confidence to…
Power Tips # 141: Tips and tricks for achieving wide operating ranges with LLC resonant converters
Inductor-inductor-capacitor (LLC) resonant converters have a couple of appealing characteristics for applications requiring an isolated DC/DC converter such as minimal switching losses, no reverse recovery when operating below the resonant frequency and the ability to tolerate large leakage inductance within the transformer. The challenge A primary challenge when designing an LLC converter with a wide…
