We started with installing python OpenCV on windows and so far done some basic image processing, image segmentation and object detection using Python, which are covered in below tutorials:

Analyzing circuit network is a crucial part in designing or working with pre-designed circuits, which deals with current and voltage in each node or branch of circuit network. However, this analyzing process to find out current, voltage or wattage of a node or branch, is a bit complex as lot of components are connected together. Proper analyzing also depends upon the…

We started with learning basics of OpenCV and then done some basic image processing and manipulations on images followed by Image segmentations and many other operations using OpenCV and python language. Here, in this section, we will perform some simple object detection techniques using template matching. We will find an object in an image and then we will describe its…

Analyzing a circuit network and finding out the current or voltage is a tough job. However, analyzing a circuit will be easy if we apply the proper process to reduce complexity. The basic circuit network analyzing techniques are Mesh Current Analysis and Nodal Voltage Analysis.

Mesh and…

In simple terms, the oscillator is a circuit which converts DC power from the supply source to the AC power to the Load. Oscillator system is built using both active and passive components and it is used for the production of sinusoidal or any other repetitive waveforms at the output without any application of an external input signal. We discussed few oscillators in our…

In the previous tutorial, we saw how a Dual Power Supply Circuit is designed. Now, we learn about Dual Converters, which can convert AC to DC and DC to AC at the same time. As the name suggests, Dual Converter has two converters, one converter works as a rectifier (Converts AC to DC) and the other converter works as an inverter (converts DC into AC). Both converters are…

An oscillator is a mechanical or electronic construction which produces oscillation depending on few variables. We all have devices which need oscillators like a traditional clock or a wristwatch. Various types of metal detectors, computers where microcontroller and microprocessors are involved use oscillators, especially electronics oscillator which produces periodic…

In power systems, harmonics are defined as positive integer multiples of the fundamental frequency. Harmonic is a voltage or current occurs at a multiple of the fundamental frequency. It is often regarded as noise in the power line.

The harmonics in the power system can be classified into two types: current…

DIAC is a semiconductor device which has three layers and two junctions. The word DIAC consists of two parts, DI and AC. The DI stands for the diode (or two. Like Di, Tri, Quad, Penta etc.) and AC stands for Alternating Current. DIAC is the acronym of the diode for alternating current.

In the below image the DIAC…

In the previous tutorials, we have learned about OpenCV and done some basic image processing and then in next tutorial we have done some image manipulation in OpenCV like cropping, rotation, image transformation etc. So in continuation with previous Image Manipulation tutorial, here we learn some more image manipulation techniques like and at the end of the…

There are lots of factories and plants in the world which use a different type of high power motors. Due to the high power consumption, the factories and plants end up paying a high amount of energy bills. To overcome the high power consumption and to increase the efficiency, VFD was introduced four decades ago but the circuitry was not strong enough.
