An inverter is a circuit that converts Direct Current (DC) to Alternating Current (AC). A PWM inverter is a type of circuit that uses modified square waves to simulate the effects of Alternating Current (AC), which is suitable for powering most of your household appliances. I say most-of because there generally exist two types of inverters, the first type is the so-called a modified square […]

Buck-Boost regulator is made using two different topologies, as the name suggests, it consists of both buck and boost topology. We already know that Buck Regulator Topology provides a lower magnitude of output voltage than the input voltage, while a Boost Regulator Topology provides a higher magnitude of output voltage than the provided input voltage. We have already built

A buck converter (step-down converter) is a DC-to-DC switching converter that steps down voltage while maintaining a constant power balance. The main feature of a buck converter is efficiency, which means with a buck converter on board, we can expect extended battery life, reduced heat, smaller size, and improved efficiency. We previously made a few simple Buck converter

In a previous article, I have shown you how you can build your own switched capacitor voltage converter circuit using the classic industry-standard LMC7660 IC. But oftentimes there are situations when you don’t have a specific IC available or the cost of an additional IC is ruining the harmony of your BOM. And this is where our beloved 555

A rectifier is a circuit that converts alternating current (AC) to Direct current (DC). An alternating current always changes its direction over time, but the direct current flows continuously in one direction. In a typical rectifier circuit, we use diodes to rectify AC to DC. But this rectification method can only be used if the input voltage

Sometimes, we might need an AC bulb flasher circuit that can blink a series of bulbs in a particular time interval for decorative purposes. By controlling the flashing time interval and sequence, we can make a series of bulbs look beautiful for outdoor decoration in Cafeteria, Restaurants, etc. or even used it for heavy Christmas light decoration,

A crude way to power your DC circuits with AC mains is to use a step-down transformer for stepping down the 230V mains voltage and adding a couple of diodes as a bridge rectifier. But due to the huge space size and other drawbacks, it cannot be used for all purposes. Another most popular and professional

Tone control or Active equalizer circuit especially bass, treble, and MID control based Equalizer is an important circuit in audio amplifier design. Generally, three-stage active Equalizer filters require three control bass, treble, and MID. The bass control allows the low frequency to pass but blocks high frequency and the treble control allows the high frequency to pass
