What Is a Switching Power Supply (SMPS)? A Definitive Engineer’s Guide Tuesday, March 25, 2025
A switching power supply (often abbreviated SMPS for switched-mode power supply) is an electronic power converter known for efficiently transforming AC power into stable DC voltage through rapid switching techniques. But what exactly makes it 'switching,' and why has it become so essential for modern electronics? Why Is It Called a “Switching” Power Supply? Unlike linear power supplies, which …

Parallel Power Supplies: A Complete Guide to Increasing Current Capacity and Reliability Wednesday, March 19, 2025
Introduction In many test and industrial applications, a single power supply may not provide enough current to meet system demands. Connecting power supplies in parallel is a practical solution that allows users to increase available current while maintaining a stable voltage. This technique can also improve system redundancy, reducing the risk of downtime due to power failures. In this guide …

Scope ADC Resolution is Nothing Without Good Probes Thursday, September 19, 2024
Key Factors Determining the Accuracy of Electrical Signal Measurement Measurement accuracy is often misunderstood as being solely dependent on the specifications of the instrument, such as the number of waveforms displayed on its screen. However, true accuracy is much more complex. It is closely tied to how well the measurement setup preserves the integrity of the signal being measured. The …

Energy Storage Devices: a Battery Testing overview Wednesday, July 28, 2021
Energy storage device testing is not the same as battery testing. There are, in fact, several devices that are able to convert chemical energy into electrical energy and store that energy, making it available when required. Capacitors are energy storage devices; they store electrical energy and deliver high specific power, being charged, and discharged in shorter time than batteries, yet with …

How to Measure a MOSFET I-V Curve
Cách đo đường cong MOSFET I-V Thursday, May 27, 2021
Một trong những cách tốt nhất để đảm bảo MOSFET hoạt động bình thường và đáp ứng các thông số kỹ thuật là xác định các đặc điểm bằng cách vẽ đường cong IV. Có một số đặc điểm đầu ra yêu cầu thử nghiệm I-V; bạn có thể tính toán cổng rò rỉ, điện áp đánh thủng, điện áp ngưỡng, đặc tính truyền tải và dòng điện suy hao bằng cách chỉ cần theo dõi các đặc tính I-V và xác minh thiết bị đang hoạt động như …
