How embedded resistor foils boost high performance in electronics

In the PCBA industry, power applications with heat transfer challenges are everywhere—power supplies, motor drives, RF amplifiers, EV systems, and high-power LED lighting, to name a few. When boards handle high currents and voltages, they generate heat that—if unmanaged—can reduce efficiency, shorten component life, or even cause outright failure. That’s why advanced thermal management is essential. At 𝗔𝗻𝗮𝗹𝗼𝗴 𝗧𝗲𝗰𝗵𝗻𝗼𝗹𝗼𝗴𝗶𝗲𝘀, 𝗖𝗼𝗿𝗽.

Silver-based sintering has long been the material of choice for mounting power chips, prized for its excellent thermal and electrical conductivity. However, evolving cost, sustainability, and manufacturing considerations are reshaping this landscape. Copper, supported by advances in pressure-assisted sintering, is now emerging as a strong alternative. It offers comparable performance, improved mechanical reliability, lower environmental impact, and a more accessible cost profile. As wide bandgap (WBG) device packaging pushes for higher efficiency and sustainability, the balance between silver and copper is becoming a pivotal discussion point for the electronics manufacturing industry.

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

Power design might be the smallest part of your system, but it is the biggest reason launches get delayed. Too often, teams rush past critical integration steps and run into the same problems: thermal derating under real-world loads, mismatched compliance across regions, and late-stage EMC failures. Each mistake means lost time, higher costs, and painful redesigns. The smarter path is simple: start with pre-certified modules, run early simulations with digital twins, and validate against worst-case scenarios from day one.

Let’s talk about how. #oemdesign #powerintegration #hardwareengineering #productdevelopment #certificationreadiness #digitaltwin #smartpower #emccompliance

🔌What Is a DC Inrush Current Limiter? When you turn on a DC device, there's a huge, brief spike in current called inrush current. This surge can damage components or blow a fuse. A DC Inrush Current Limiter acts as a buffer. It manages this initial current spike, allowing it to ramp up smoothly. This prevents damage, protects your circuit, and ensures a reliable startup every time. Don't overlook this small but vital component in your DC power designs!

Shunt Resistor – A Simple Component with a Powerful Role In electronics, sometimes the smallest components do the biggest jobs. A shunt resistor is one such example — crucial for current measurement and circuit protection. What is a Shunt Resistor? A low-value precision resistor placed in parallel (or sometimes in series) with a circuit path to create a measurable voltage drop that is proportional to current. Why It’s Important: 1️⃣ Current Sensing – Converts current into voltage (using Ohm’s Law). 2️⃣ Protection – Prevents overcurrent by enabling monitoring/control. 3️⃣ Accuracy – Used in precision power supplies, battery management, and energy meters. Key Considerations in Design: Resistance Value (mΩ range) – Must be low enough to minimize power loss but high enough to generate measurable voltage. Power Rating – Handles heat dissipation under high currents. Temperature Coefficient – Stability matters in precision systems. Real-World Applications: Battery management systems (BMS) in EVs. Power monitoring in embedded devices. Industrial automation for current feedback. Takeaway: The shunt resistor may look tiny, but it’s the eyes of the circuit — allowing us to “see” current and keep systems safe and efficient. #Electronics #CircuitDesign #ShuntResistor #Engineering

Stepping into Transfer Functions of a Buck in DCM: Part 4 of 6 Welcome to the intricate world of power electronics, where the buck converter's performance can be finely tuned by understanding its different conduction modes. In this segment, we will examine the detailed steps involved in deriving the transfer function for a buck converter operating in DCM, utilizing various methods. This journey will not only reveal the complex relationship between the input and output voltages but also confirm that the buck converter in DCM still performs its essential step-down function. When we create a transfer function, the load current (and other parameters) will come into play.  https://lnkd.in/epP3KXw9 #aheadofwhatspossible #analogdevices
