Opting for such filters keeps you from getting locked into paying for power factor correction — an unnecessary feature in commercial facilities — like you can when using passive filters. Not only that ...

Today I am experimenting with a single chip Universal Active Filter, in this case I made a small PCB for the UAF-42 from Texas Instruments. I chose this part in particular as it facilitates setting… ...

What do you really get using a supplier tool for an multiple feedback (MFB) low pass active filter? Let's continue the quest for the best results using the example designs from Part 1. In this online ...

The classical approach to arranging an odd-order, low-pass active filter is to place the single pole of the odd-ordered filter at the front-end of the circuit. Following this first stage there are the ...

In the last video I demonstrated a Universal Active Filter that I could adjust with a dual-gang potentiometer, here I replace the potentiometer with a processor controlled solid-state ...

Depending on AFE/AIC versions, the LCL filter can be selected with (see diagram) or without series RC passive dampers – the later, for example, for motor drives that have built-in active damping.

For example, John Deere IT4 machines have a monitor with comprehensive exhaust filter-related operation and maintenance information, including a soot-level indicator. The easy-to-read indicator ...

Scientists in the Middle East have developed a series active filter to improve power quality in grid-tied PV systems, consisting of an inductor, two capacitors, and four transistor-diode pairs ...
