In this post I will explain how to use this active PFC calculator for calculating high current, high PFC designs. In our example we will be using 230 VAC input and 3 kW output and Vout equal to around 390 V, and we will try to see how each resistor and capacitor gets calculated in […]
Newly Updated Circuit Projects:
Can EGS002 Work With a Standard 16×2 LCD?
Many people build inverter using EGS002, then they ask can we connect normal 16×2 LCD or not?? So the answer is yes, but not the way you may think. Understanding LCD Side Of EGS002 As we all know EGS002 is built around EG8010. That chip is dedicated SPWM sine wave inverter controller IC, which handles […]
TENS Circuit for Dry Mouth Xerostomia Relief Using Parotid Gland Stimulation
We are getting many genuine requests from elderly readers who are suffering from different health related problems and one very painful condition among them is Dry Mouth also called Xerostomia. Real Life Dry Mouth Problem One of our respected readers from South Africa who is now 76 years old shared his real life suffering with […]
How to Use IC LM393 as a Current Controller Circuit
In this post we will understand a current controller and current limiter circuit using the IC LM393 comparator. This circuit is using a low power voltage comparator integrated circuit LM393 and one power Metal Oxide Semiconductor Field Effect Transistor, so the idea is simple but the working looks a little deep when we see it […]
Simple 220V AC Fan Regulator Circuit using Push Button
In this post we learn about this 220V AC electronic fan regulator circuit using a push button which changes speed step by step with each press. We press the button, then circuit cleans the signal, counts it properly, and then selects a relevant fixed speed level. Each button press moves the fan from OFF to […]
Control a Relay ON OFF Using SIM Card, Mobile Phone, and Arduino
This project I will explain how we can control a relay remotely using a SIM card and a normal mobile phone, with help of Arduino and a GSM module. The relay can be turned ON or OFF by sending an SMS or by making a phone call to the SIM card placed inside the GSM […]
