Here we will learn this current sensing technique in detail and wire up a current transformer to measure AC current with the help of an Arduino. We will also learn to determine the turns ratio of an ...

It needs two capacitors for filtering the power supply and output while requiring a power supply of 5V. For 5A model, the value that links the proportionality of output voltage and input current ...

After harvesting a flyback from the power board of a CRT, [Andrew Moser] added a new primary coil to the transformer. This boosts 12 volts that can be easily controlled by an Arduino to something ...

Arduino Program for SPWM Inverter. Before we go ahead and start to understand the code, let's clear out the basics. From the above working principle, you have learned how the PWM signal will look like ...

In this paper, a Printed Circuit Board (PCB) Planar Current Transformer is proposed for GaN synchronous rectifier. This type of current driven synchronous rectifier is also known as the “Active Diode” ...

Assemble the circuit on the designed PCB. Once the circuit is ready and Arduino sketch is written to the board through USB port, connect shorting jumper SJ1 and a multimeter in place of the battery ...

How it works: A Regulated Power Supply (RPS) is one which converts your AC mains into DC and regulates it to our required voltage level. Our RPS uses a 24V 3A step down transformer which is rectified ...

In planar transformers, windings are made of printed circuit board layers, and circulation currents lead to severe unbalance of current sharing between parallel layers. This paper presents an ...

Like many hackers, [Matthias Wandel] has a penchant for measuring the world around him, and quantifying the goings-on in his home is a bit of a hobby. And so when it came time to sense the current … ...
