⚡Why does a diode allow current in one direction but block it in the other? The answer lies in its I-V characteristics! 📉⚡ 🔁 Understanding the Current-Voltage (I-V) curve of a diode is crucial for designing rectifiers, regulators, and switching circuits. Let’s break it down! 📌 Key Regions of the I-V Curve ✅ Forward Bias Region (+V, +I) ⤷ Small current flows until threshold voltage (Vₜ) is reached ⤷ Silicon diode: ~0.7V | Germanium diode: ~0.3V | LEDs: ~1.8V - 3.5V ⤷ After Vₜ, current rises exponentially ✅ Reverse Bias Region (-V, ~0I) ⤷ Minimal leakage current flows (almost no conduction) ⤷ Acts as an open circuit ✅ Breakdown Region (-V, High -I) ⤷ If reverse voltage exceeds limit, breakdown occurs ⤷ Zener diodes are designed to operate in this region for voltage regulation 📊 Where Are These Curves Used? ⤷ Rectifier Circuits → Convert AC to DC ⤷ Voltage Regulators → Maintain steady voltage (Zener diodes) ⤷ LED Circuits → Light emission for indicators & displays ⤷ High-Speed Switching → Schottky diodes for fast response 💡 Choosing the right diode requires understanding its I-V curve! Engineers use this data to optimize circuit performance and efficiency. ➡ What’s your go-to diode for circuit design?

The AWG number is inversely proportional to the wire's size. So, a lower AWG number means a thicker wire that can handle more electrical current. 🔌 12 AWG: Thick and perfect for general power outlets. 💡 14 AWG: A bit thinner, great for lighting circuits. 🔊 18 AWG: Thinner still, ideal for low-voltage things like speakers. Choosing the right gauge prevents overheating and ensures your devices get the power they need to run efficiently. #TechExplained #Engineering #Electrical #WireGauge #StayConnected #Science #DIYProjects #lcscelectronics #cable

At their core, Static Frequency Converters (SFCs) rely on the classic AC → DC → AC conversion chain: First the rectifier stage converts the incoming AC supply into DC, then the DC link that is mainly capacitors and filters is responsible of stabilizing the power.after that is the Inverter stage that reconstructs AC at the desired frequency and voltage. From a control engineering perspective, the challenge lies in: Maintaining low harmonic distortion (THD) on both input and output. Ensuring voltage and frequency stability under varying loads. Designing robust control loops (often based on PWM techniques, vector control, or even model predictive control) to handle nonlinear dynamics. Managing power factor correction and minimizing losses. Applications range from 400Hz ground power units in aviation to ensuring 50/60Hz interoperability in global manufacturing. It’s a perfect example of how control theory, power electronics, and practical engineering come together to solve real-world problems. #PowerEngineering #ControlSystems #PowerElectronics #StaticFrequencyConverter

⚡ Active or Passive Component: Do You Think You Know the Difference? In this 2nd post of my series on PID control in electronics, I propose to look at this distinction from a much more practical angle. We all learn that: • 🔹 A passive component consumes energy (resistor, lamp, capacitor…). • 🔹 An active component uses a power supply to amplify or generate a signal (op-amp, transistor…). Simple, right ? Well… not really. 👉 So how can a passive circuit perform the same function as an active one, even though their nature is completely different? 🤔 When we apply this difference to an electronic PID, the impact is immediate: • ⚙️ Passive → simple, cost-effective… but inevitable losses. • ⚙️ Active → amplification, better precision… but watch out for saturation! ❗ Before designing a PID, don’t forget to: 1️⃣ Study the system stability (open-loop and closed-loop) 2️⃣ Calculate the P, I, and D coefficients (tuning) 3️⃣ Then build the circuit. 🎁 In this post, I share with you a practical document that includes: • Simple & beginner-friendly guide to designing P action in electronic. • LTspice simulations to visualize the electronic parameters. • Falstad demos to test passive vs. active in real time. 💬 And you? Do you know how to reduce voltage drop in a purely passive circuit (at least for small loads) 🤔❓ 📌 Additional resources: 👉 Part 1 - Intro to PID controller : https://lnkd.in/enD9aMhq 👉 Falstad Demo (Passive Implementation) : https://lnkd.in/eGewaKQY 👉 Falstad Demo (Active Implementation) : https://lnkd.in/eJyndKS6 #Electronics #Automation #Engineering #PID #Controller #ControlSystems #EmbeddedSystems #LTspice #Falstad

High Power Density is a Trend — But Balance is the True Goal ⚡ In test power supplies, power density has become a major focus. Packing more kilowatts into fewer liters means better space utilization and efficiency — a clear advantage for R&D labs and system integration. But density alone is not enough. A truly robust solution must also balance performance and long-term reliability. Without this balance, higher density can quickly turn into higher risk. In practice, high-density designs must be supported by advanced capabilities, such as: 🔎 Four-quadrant operation → enabling bidirectional power flow for complex test scenarios 🔎 Programmable waveforms with feedback → simulating diverse conditions with high accuracy 🔎 Modular scalability → supporting multi-unit parallel connection and future expansion 🔎 Integrated AC source + load design → reducing system complexity, cabling, and cost 🔎 Fast dynamic response → ensuring precise performance in demanding applications An example is the ActionPower PRE20 Series, which integrates 22 kVA in just 3U (≈133 mm) — reaching nearly 950–1100 W/L, a level that stands among the industry’s best. Importantly, this density is achieved together with dynamic performance, functional integration, and stability, making it suitable for advanced applications like battery simulation, grid emulation, and high-end validation. 👉 In the end, high power density matters — but true engineering excellence lies in achieving density, performance, and reliability together. #HighPowerDensity #PowerTesting #Electronics #ActionPower

Did you know that a tiny component is crucial for managing the massive electrical currents powering our world? In the vast landscape of electronics, DC shunts play an indispensable role, often working behind the scenes to ensure safety, accuracy, and efficiency. But what exactly are they, and why are they so important? A DC shunt is essentially a very low-resistance resistor designed to carry large direct currents (DC). Its primary function is to create a measurable voltage drop proportional to the current flowing through it. According to various electronics resources, this voltage drop then allows a measuring instrument, like an ammeter or a multimeter, to accurately determine very high currents without having the full current flow directly through the instrument itself, which could damage it or provide inaccurate readings. Here's why they are so vital across various applications: 1. Accurate Current Measurement: They enable the safe and precise measurement of currents far beyond what standard meters can handle, from industrial machinery to automotive systems. 2. Circuit Protection: By providing a known point for current sensing, shunts can be integrated into overcurrent protection circuits, safeguarding valuable equipment from damage. 3. Battery Management Systems (BMS): In electric vehicles, solar power setups, and uninterruptible power supplies (UPS), DC shunts are critical for monitoring charge and discharge currents, optimizing battery life and performance. 4. Power Supply Monitoring: They are essential in power supplies to ensure stable and controlled current output, vital for sensitive electronic devices. 5. Efficiency & Safety: Accurate current monitoring contributes to greater system efficiency by preventing overload and ensuring components operate within their specified limits, enhancing overall safety. From large industrial power systems to the compact electronics in our everyday devices, DC shunts are fundamental components that quietly ensure our electrical world runs smoothly and safely.
