Rectifier A rectifier is an electrical circuit or device that converts periodically reversing alternating current (AC) into unidirectional direct current (DC). Rectifiers have numerous applications, although they are most commonly encountered as components of DC power supplies and high-voltage direct current power transmission systems. Rectification can be used for purposes other than generating direct current for use as a power source. There are two types of rectifier circuits: 1) Half wave rectifier and 2) Full wave rectifier. Half Wave Rectifier When a AC waveform is applied and when half of the AC cycles gets rectified, it is called as half wave rectifier. The output voltage of the half wave rectifier is not pure DC as the AC components are present in this voltage. This AC component is called as ripple voltage. In half wave rectification, the rectifier only conducts during the positive half cycles of the alternating current (AC) supply. During negative half cycles, no current is c...

  Author: Manikandan KJ © KJMIndia Automatic water level controllers regulate the water supply for a given reservoir/tank to maintain a minimum water level. This  water level controller circuit uses a float switch to control the water level of the storage tank. It is an automatic system, so it will start to fill up when the height of the water goes below a certain point. If it reaches full capacity, the float switch will automatically turn off. This protects against overfilling and spilling of water. The water level controller manages the level of water in a tank. It automatically detects the tank's water level and turns the pump on or off to maintain it at the desired level. The float switch helps detect different levels of water by using a magnetic switch module that floats on top of the water. FEATURES OF THIS CIRCUIT: ( Click here to buy the ready-made kit) Low-cost circuit made out of readily available components. Low power consumption. Turns on the pump when ...

    Author : Manikandan K J    Circuit Sponsor : kjmindia.in Water level controller is necessary for many reasons. Water level can be monitored and controlled automatically without any human intervention. Thus, it saves water wastage, electricity and time. This can be used both in industries and houses. The circuit I am going to share in this post controls water level in the overhead tank or any tank. Can be used in tanks of any liquids (eg. oil) provided it should not be hot. The cost of making this circuit is very low and can be assembled on a general purpose board if you are using it for your personal use. For commercial purposes, you can buy one from here . Working of the circuit: This circuit is controlled by a single NPN transistor with the help of two cable float switches. It will constantly monitor both the levels of sump and overhead tank and protects the motor pump from dry run. The unregulated DC voltage from the transformer is regulated by the volta...

Author : Manikandan K J Benefits of Power failure and resumption alarm: Power failure and resumption alarms are vital instruments that offer a multitude of advantages in many environments. The purpose of these alarms is to notify individuals or organisations in the event of a power outage and subsequent restoration of electricity. The incorporation of these warnings into various systems presents multiple benefits, which include: 1. The safeguarding of equipment: Power outages can result in adverse consequences for delicate equipment, including computers, servers, and medical apparatus. The timely notification of individuals to a power outage facilitated by these alarms enables swift response measures, such as the cessation of equipment operations or the initiation of backup power systems. This measure serves to mitigate harm and probable loss of data, so safeguarding the durability and dependability of valuable equipment. 2. Safety and Security: The occurrence of power outages ...
