The coil connected to the source is called primary winding and the other one is called the secondary winding. The coils are insulated from each other and from the core. If a transformer receives energy at a low voltage and delivers it at a higher voltage, it is called step up transformer.
When a transformer is supplied some lower voltage, it is called a step-down transformer. We used a step-down transformer in the circuit.
For an autotransformer, the secondary winding is actually part of the primary winding. The rectifier circuit is the process of converting an alternating ac voltage into one, that is limited to one polarity.
Rectifier circuit that contains diode is called rectifier diode.
The diode can pass current easily in one direction only. The rectifier circuit is classified as half-wave and full-wave rectifier.
The output voltage appears only during the positive cycle of the input signal, the circuit is called a half-wave rectifier. A rectifier output voltage occurs during both the positive and negative cycles of the input signal, this circuit is called a full-wave rectifier. Full-wave rectifier consists of a Central-tapped full-wave rectifier; and b Bridge full-wave rectifier.
We used Bridge full-wave rectifier. Schematic Circuit Diagram of Rectifier Filter circuit provides a constant voltage to a load. Power diodes are usually constructed using silicon and germanium.
Silicon diode can operate at higher current and at higher junction temperature, and they have greater reverse resistance.
The structure of a semiconductor diode and it symbol are shown in Figure. The diode has two terminals, an anode, A terminal P junction and a cathode K terminal N junction. When the anode voltage is more positive than the cathode, the diode is said to be forward biased and it conducts current readily with a relatively low voltage drop. When the cathode voltage is more positive than the anode, the diode is said to be reverse biased, and it blocks current flow.
The arrow on the diode symbol shows the direction of convection current flow when the diode conducts. This circuit can be used for calling Bell or the emergency etc. IC1 produce the low-frequency square wave pulses that can be used as the oscillator and IC2 also work for the high-frequency oscillator.
At low state IC1 output reach 0V and the ground will be simultaneously cut off. In this way, the output signal high frequency of IC2 will cause the sound that is simultaneously cut off. This will draw the attention of other passengers and the burglar can be caught red handed.
In the standby mode, the circuit is locked by a plug and socket arrangement a mono plug with shorted leads plugged into the mono-jack socket of the unit. Automatic Plant Watering System : This one of the most useful project in our real life. It helps us in watering plants automatically without any human interference.
We may also call it as Automatic plant irrigation system. We know that people do not pour the water on to the plants in their gardens when they go to vacation or often forget to water plants. As a result, there is a chance to get the plants damaged. This project is an excellent solution for such kind of problems. Water Level Indicator : The Water Level Indicator employs a simple mechanism to detect and indicate the water level in an overhead tank or any other water container.
The sensing is done by using a set of nine probes which are placed at nine different levels on the wall of the tank with probe1 to probe8 placed in ascending order of height, common probe i. It can also be used as fuel level indicator in vehicles.
IR Remote Control Switch : By using this circuit, we can control any house hold appliance with the help of remote. Electronic appliances like television, radio, air conditioner etc.
In this project, there are two parts: one is the transmitting section remote and the other is receiving section which is stable and connected to the appliance. Using this circuit, we can automatically charge a battery when its charge is below a threshold and the circuit is disabled when the battery attains full charge.
SCR is used in rectification circuits, inverter circuits, power control circuits, etc. Stun Gun Circuit : This Stun gun circuit produces high voltage and low current signal. It is mostly used as a weapon to stun or send shock waves to the target with the intention to weaken or paralyze it. It can be use in modern warfare, protection from intruders or animals.
Variable Power Supply and Charger : This is a circuit which helps to check or test your electronic projects at your workbench and also to charge the Mobile phone batteries. This circuit is also very useful during power cuts blackouts as it can also work as an emergency light.
It can be used in appliances that require 24 V DC supply like radios, lights, automobile electronics, special purpose UPS etc. This circuit works on analog to digital conversion principle. The temperature can be displayed using an LCD. It can be used at homes, mobile places like cars to keep a track of the temperature.
Cell Phone Detector : This is a simple circuit which helps to detect the presence of an activated cell phone by detecting the signals in the frequency range of 0. It helps in tracking mobile phones particularly in examination halls or important conferences.
It can also be used to detect the mobile phones of spies or in case of unauthorized data transmission. The radius of this detector is 1. Temperature Controlled DC Fan using Microcontroller : The main principle of the circuit is to switch ON the fan connected to DC motor when the temperature measured through a temperature sensor is greater than a threshold value. This can be used in home applications particularly in CPU to reduce heat by automatically switching ON the fan.
Stress Meter : This stress monitor lets you assess your emotional pain. It can indicate three levels of stress: Relaxed, Moderate and High levels with the help of a series of LEDs combination of green, yellow and red.
If the stress is very high, it gives visual indication through the LED display along with a warning beep. The gadget is small enough to be worn around the wrist. Bidirectional Photoelectric System : Photoelectric detectors are usually unidirectional i. On the contrary, a system able to detect movement in both directions could be useful to control shops, rooms etc. If installed in a shop it could allow knowing if all customers entering the premises have left them at the end of the day.
Or, at home, it could be used to switch on the light or any other electric device when one enters the room and to switch off the electric device when he or she leaves it.
Additionally it can be used to control the number of people as this circuit switches off the electrical device only after the last person leaves the area. Self-powered Fast Battery-Tester : This circuit runs a fast battery test without the need of power supply or expensive moving-coil voltmeters. It features two ranges depending on the position of the switch. In one position, the device can test 3V to 15V batteries and when the position of the switch is changed, only 1.
A set of LEDs are used to indicate the charge of the battery i. It boosts the FM reception by amplifying the weak FM signals. Self-Powered Door Bell Watcher : This very simple and self-powered device was conceived to allow a person to monitor if someone has rung his home door-bell when he was out.
The circuit must be simply connected to the two door-bell-coil leads. An LED or a buzzer or both can be used to indicate the event event is door-bell being pressed. It can store the event for a minimum of 15 days. It can be used for any mains supplied device like computer, television etc. Fridge Door Alarm : This fridge door alarm is a light sensing circuit. It should be placed in the fridge enclosed in a small box near the lamp or close to the opening. When the door is opened, the light from the lamp or outside will fall on it and the buzzer goes off for a certain time and stops.
This process repeats until the door is closed. This circuit is useful when the fridge door is not closed or it is kept open for a long time. There are many systems that convert wind energy to electrical energy.
A direct driven permanent magnet generator has been designed specifically for vertical axis wind turbine. The generator maintains high efficiency and has high torque capability for the entire operational regime. Energy Leak Detector : This circuit is primarily used to detect draughts around doors and windows which cause energy leaks. This circuit is essentially a temperature sensor and can be used where sensitive temperature detection is needed.
It makes use of a comparator and detects the slight changes in temperature by comparing it to room temperature ambient temperature. Infra-red Level Detector : This circuit is a level sensor or proximity sensor. It can be used to detect the level of a liquid in a tank without any contact.
