𝐄𝐱𝐜𝐥𝐮𝐬𝐢𝐯𝐞 𝐀𝐧𝐚𝐥𝐲𝐬𝐢𝐬 𝐎𝐧 𝐂𝐨𝐦𝐦𝐨𝐧-𝐦𝐨𝐝𝐞 𝐂𝐡𝐨𝐤𝐞𝐬 𝐌𝐚𝐫𝐤𝐞𝐭 𝟐𝟎𝟑𝟑 Common-mode chokes are inductive components that are used to suppress common-mode noise in electrical circuits. Common-mode noise is a type of interference that occurs when the same signal appears on both the power and ground lines of a circuit. Common-mode chokes are used to reduce this noise and improve the signal-to-noise ratio of the circuit. Common-mode chokes are made up of windings of wire around a ferrite core. The windings are connected in a way that allows them to create a magnetic field around the core. This magnetic field is used to impede the flow of alternating current (AC) and reduce the amount of common-mode noise that is present in the circuit. Common-mode chokes are usually rated in terms of their inductance, which is measured in Henries.

The most important parameter of power semiconductor devices reflecting their overload capacity is the surge current – the maximum permissible current amplitude of a semi-sinusoidal shape lasting 10 ms. Increasing power capacity of semiconductors and designing devices with a rectifier element diameter of 100 mm or more both require a surge current testing system that can form current pulses up to 100 kA. To solve this problem, a number of requirements must be taken into account. First, during pre-breakdown state with the so-called direct current filamentation the voltage drop across the test sample sharply increases and can reach 60V for high-voltage semiconductors. Secondly, the tester must ensure high accuracy in setting the current amplitude, since forming a current pulse with an amplitude of the order of 100 kA requires absolute deviation from the set value within 2-3 kA. Thirdly, it is necessary to ensure structural rigidity, taking into account the enormous dynamic forces arising during the current pulse. The article presents a unique surge current tester rated for 120kA, describes an innovative approach to forming the current based on MOSFETs and details the key features of its power section and the clamping device.

What is a Notch Filter? 🤔   In the electronics realm, a notch filter is crucial. Known as a band-reject or stop-band filter, it blocks or attenuates specific frequencies while letting others pass. Ideal for applications where certain frequency ranges need suppressing. 💪   Key Components 1. Passband Region: Minimal attenuation, close to 0 dB. Lets desired frequencies through with little loss. 🚀 Ensures important signals aren't hindered. 2. Stopband Region: Maximum attenuation. Blocks or reduces unwanted frequencies. 🔇 Keeps interference at bay.   Construction Made with inductors and capacitors in series and shunt configurations. A precision tool for frequency control. 🛠️   Specifications Includes stop band (identifies unwanted frequencies), passband range (ensures smooth passage of desired signals), insertion loss (minimizes signal degradation), power handling (for high-power signals), operating temperature (for reliable performance), connector type (for seamless integration), and package type (offers design flexibility). 📦   Frequency Response Shows attenuation at stopband and passage of other frequencies. Tunable notch filters are useful for fine-tuning. 🎯   Applications In radio frequency communication for noise reduction, interference suppression, and protection. In RF test labs, mobile devices, medical equipment, audio devices, and two-way radios. 📡 📱 🩺 🎶 📻   Conclusion: Notch filters are essential in many electronic systems.
