So with that in mind, in this article, we will show you how you can build a 5V, 1A SMPS circuit by salvaging parts from an old throwaway PC ATX power supply. You may not notice it but most of the household products like mobile charger, laptop charger, Wi-Fi Routers, require a switching mode power supply to operate, and most of those are 5V one.

We even did build our own SMPS transformer that could be used in our SMPS designs along with the driver IC. We have already made a few SMPS circuits earlier, like this 5V 2A SMPS circuit and 12V 1A TNY268 SMPS circuit. It is used to convert mains high-voltage AC to low voltage DC, and it does it by first converting the mains AC to high voltage DC, then switching the high voltage DC to generate the desired voltage. In the circuit, an inductor blocks DC and allows AC to flow through it whereas the capacitor blocks DC and allows AC.A Switch Mode Power Supply (SMPS) is an indispensable part of any electronic design. The act of filter mainly depends on the electrical properties of components. This circuit can be built with passive components like resistors, capacitors, and inductors. But this circuit permits the DC components to get to the load.

A filter circuit is used to eliminate the ac components within a rectifier circuit. Thus, this is all about an overview of the pi filter. Whereas, on the receiver end these filters are applicable for demodulating the exact frequency range.

In communication, the signal can be changed into several high frequencies.

This filter is mainly used for attenuating noise within signal as well as power lines.

The applications of the pi filter mainly include communication devices to retrieve the exact signal after modulation.

The applications of the pi filter include the following. The disadvantage of pi filter include the following The Advantages of pi filter include the following. = √2/8 ω 3 C1 C2LR L Advantages & Disadvantages = Idc Xc1 Xc2 √2/Idc X L = Idc Xc1 Xc2√2/Idc RLX L The ripple factor formula of the pi filter is Now V’ ac rms = V ac rms Xc2/X L = I dc Xc1√2 * Xc2/X L The ripple voltage can be attained by multiplying Xc2/XL The above equation is the i/p capacitor’s reactance at 2nd harmonic distortion. Substitute the value of ‘Vr’ in the above expression When C =C1 in the pi filter, then the RMS value of o/p voltage can be expressed as component maintains its journey toward the choke ‘L’ So, capacitor C1 avoids a considerable amount of a.c. component of rectifier o/p output as it gives unlimited reactance toward the d.c. The first filter capacitor (C1) provides small reactance toward a.c. The filtering act of these three components in the filter circuit is discussed below.

The rectifier’s output is applied across the input terminals of the filter like 1 & 2. Simply one section of the filter is shown however numerous equal sections are frequently utilized to progress the smoothing act.

Here C1 is connected across the o/p of the rectifier ‘L’ is connected in series & ‘C2’ is connected across the load. This is the reason that the circuit is named as a pi filter. These three components are arranged in the form of greek letter pi. This circuit is designed with two filter capacitors namely C1 and C2 and a choke mentioned with ‘L’. The pi filter circuit design is shown below.
