Simplest BJT CC, CV Battery Charger Circuit with Trickle Charging (Adjustable)
Today I will explain to you how this simplest constant voltage and constant current battery charger circuit works. This circuit is very nice for charging battery safely without damaging it. It has two main jobs, one is limiting high current and second is stopping over voltage. Main Parts Used In Circuit In this circuit we […]
Adding a Soft Start to Water Pump Motors – Reducing Relay Burning Problems
In this post I have explained a few innovating and simple soft start circuit examples which may be implemented with heavy duty motors so that they are able to initiate with a soft start or a slow sluggish start instead of a sudden, bumpy start Why Soft Start is Crucial for Heavy Motors When heavy […]
Prevent Relay Arcing using RC Snubber Circuits
In this article I have explained the formula and techniques of configuring RC circuit networks for controlling the arcing across relay contacts while switching heavy inductive loads. Arc suppression An arc is produced across the contacts when a switch or a relay is opened. With time, this condition can wear down the contacts. To overcome […]
Inverter Circuit with Feedback Control
In this article I have explained a couple of inverter circuits featuring an automatic feedback control for ensuring that the output does not exceed the normal specified AC output level, and also does not exceed the specified overload conditions. What is Feedback Control in Inverters A feedback control in inverter is generally incorporated to control […]
Wireless Servo Motor Control Using 2.4 GHz communication link
In this post I will show how to construct a wireless servo motor circuit which can control 6 servo motors wirelessly on 2.4 GHz communication link. Introduction The project is divided into two parts: a transmitter with 6 potentiometers and a receiver circuit with 6 servo motors. The remote has 6 potentiometers to control 6 […]
