Simple Online UPS Circuit

Last Updated on April 22, 2025 by Swagatam 39 Comments

online UPS compressed

In this post I have explained about the making of a simple online uninterruptible power supply (UPS) which guarantees a seamless transfer of AC mains supply to inverter mains supply for the load, due to the absence of cumbersome transfer switches or relays. What is an Online UPS As the name suggests, an online UPS […]

Simple Boost Converter Circuit Diagrams using Transistors

Last Updated on January 27, 2025 by Swagatam Leave a Comment

boost converter working model

In this post I have explained a few very simple boost converter circuits using only BJTs, or transistors. Let’s learn more. What is a Boost Converter A DC boost converter circuit is designed for stepping-up or boosting a small input voltage levels to a desired higher output voltage level, hence the name “boost” converter. Since […]

2 Simple Voltage to Frequency Converter Circuits Explained

Last Updated on January 19, 2025 by Swagatam 7 Comments

C2

A voltage to frequency converter circuit converts a proportionately varying input voltage int a proportionately varying output frequency. The first design is using the IC VFC32 which is an advanced voltage to frequency converter device from BURR-BROWN specifically designed to produce an extremely proportional frequency response to the fed input voltage for a given voltage […]

2 Simple Milliohm Meter Circuits [Measure Low Resistances below 1 Ohm with these Circuits]

Last Updated on January 19, 2025 by Swagatam 5 Comments

low ohm tester circuit compressed

The low resistance measuring circuit I have explained below can be used for measuring all milliohm resistances below 1 ohm with extreme accuracy. The resistance to be measured can be as low as 0.01 ohm or 10 milliohm. The output of the circuit converts the resistance value to exactly equivalent volts, which means the output […]
