How to Build a 1000W ZVS Induction Heater Using a Resonant RLC Circuit – Open Electronics
Let’s Melt Metals Using the ZVS (Zero Voltage Switching) Technique Applied to a 1,000W RLC Resonant Circuit Have you ever wondered how intense the electromagnetic fields surrounding us can be? This is a relevant question, considering we are surrounded by countless electromagnetic waves, caused by power distribution cables, radio and TV transmitters, mobile phone networks,…

The CyberPower DBH361D12V2: An UPS That Goes Old-School
Normally, when I cover the topic of uninterruptible power supplies (UPSs), I’m talking about devices containing rechargeable battery packs based on either sealed lead-acid (SLA) or one of several newer lithium-based charge storage technology alternatives. But what if the backup-power unit’s batteries aren’t rechargeable…and are lowly alkaline D cells (aka, IEC 420s)? Normally, I’d probably…

“Beyond Technology; We Offer Complete Ownership And Modernisation Of The Parking Operations”- Dhananjaya Bharadwaj, ParkMate
– Advertisement – Long queues, disorganised space, congestion; parking in India is often really chaotic. Recognising this issue, Dhananjaya Bharadwaj from ParkMate shares everything about their advanced, entirely ‘Made-in-India’ automated solution with EFY’s Nitisha Dubey. Dhananjaya Bharadwaj (Right), Co-founder & CEO, ParkMate Q. Can you share an overview of ParkMate and the solutions it provides?…

Power Tips #142: A comparison study on a floating voltage tracking power supply for ATE
In order to test multiple ICs simultaneously with different test voltages and currents, semiconductor automatic test equipment (ATE) uses multiple source measurement units (SMUs). Each SMU requires its own independent floating voltage tracking power supply to ensure clean measurements. Figure 1 shows the basic structure of the SMU power supply. The voltage tracking power supplies…

Oscilloscope input coupling: Which input termination should be used?
Getting signals into an oscilloscope or digitizer without distorting them is a significant concern for instrument designers and users. The critical first point in an instrument is the input port. Oscilloscopes offer 50-Ω and 1-MΩ input terminations for both channels and trigger inputs. When should each be used? A typical oscilloscope offers input ports terminated…

Reimagining Future Work And Play With XR Technologies
– Advertisement – Integrating AI and 5G, A convergence of virtual, augmented, and mixed realities is redefining industries and positioning XR as a cornerstone of India’s digital transformation. Extended reality (XR), an umbrella term encompassing virtual reality (VR), augmented reality (AR), and mixed reality (MR), is rapidly transforming the way we interact with the digital…

Computer and network-attached storage: Capacity optimization and backup expansion
Motivations for bolstering backup Last March, I documented my travails striving to turn a 2018-era x86-based Apple Mac mini into a workable system in spite of its diminutive, non-upgradeable 128 GByte SSD’s internal capacity: Eight months later (last November), I discussed how, motivated by the lightning-induced last-summer demise of one of my network-attached storage (NAS)…

LED Pixel Lighting: Promising Brighter Automotive Lighting
– Advertisement – Reimagining headlights as smart, stylish, and sustainable systems, LED pixel lighting is transforming how vehicles see and are seen, blending safety, design, and cutting-edge control. An LED pixel light controller is an electronic device or system that manages and synchronises the colour, brightness, and pattern of LED pixels in a vehicle’s lighting…

Ray-Ban Meta’s AI glasses: A transparency-enabled pseudo-teardown analysis
A look at AI glasses I’ve been following smart glasses for a while now (and the more embryonic camera-augmented eyewear category a “bit” longer than that). As with smart watches and more recent smart rings, they’re intriguing to me because they take already-familiar, mature and high volume consumer products and make them…umm…smart. Plus, there’s the…

New EDA tools arrive for chiplet integration, package verification
The world we are living in is increasingly becoming software-defined, where artificial intelligence (AI) is adding the next layer of functionality. And it’s driving the need for more compute to enable the software-enabled functionality. However, with this huge progression in compute content, Moore’s Law scaling will be insufficient to support the number of transistors for…
