LC Filter CircuitĪn LC-filter is constructed by combining an inductor in series with the load, and a capacitor in parallel with the load. In our previous tutorials on inductor filters and capacitor filters, we learned that each type of filter improves the signal quality, and that they do so in different ways. Higher quality filters can feature multiple stages involving inductive and capacitive elements to carefully filter the output. Inductors and capacitors can both be used as filters, both individually and in combination with each other. Filters can be used after rectification in order to improve the quality of the output signal. We need a way to flatten out the pulsed DC waveform. This is an important step in AC-DC conversion, but common electronic devices require a steady, flat DC signal. A rectifier is a circuit that takes a sinusoidal AC input and outputs a pulsed DC waveform using diodes. The most common way to convert an AC signal into DC is by using a rectifier. LC filter circuits are also used in low-pass, high-pass, band-pass, and band-stop filter applications. We will learn about the uses of an LC filter, operational theory, and application in power supplies. In this article, we will cover LC Filters to improve the output of rectifiers. LC filters combine the attributes of both inductor filters and capacitor filters, improving the output quality to a greater extent than either individually.
