High Intensity Discharge lamps (HID) used for urban street light are based on principle of gas discharge, thus the intensity is not controllable by any voltage reduction method as the discharge path is broken. In this project White Light Emitting Diode (LED) replaces the HID lamps where intensity control is possible by Pulse Width Modulation (PWM). The intensity control helps in saving energy at late nights during which the traffic density is low. A programmable microcontroller from 8051 family is engaged to provide different intensities at the different times of late night for energy saving. The intensity gradually decreases from full intensity and then finally OFF. The power supply consists of a step down transformer 230/12V, which steps down the voltage to 12V AC. This is converted to DC using a Bridge rectifier. The ripples are removed using a capacitive filter and it is then regulated to +5V using a voltage regulator 7805 which is required for the operation of the microcontroller and other components.

Model no: 2 The aim of this project is control the speed of DC motor. The speed of DC motor is directly proportional to the DC voltage applied across its terminals. Hence, if we control the voltage applied across its terminal, we actually can control its speed. Here we use microcontroller from 8051 family. Two buttons are used as inputs to control the speed of motor. PWM is generated at the output by using program burned into the microcontroller. The program can be written in Assembly language or in Embedded C. PWM (Pulse Width Modulation) wave can be used to control the speed of the motor. Here the average voltage given or the average current flowing through the motor will change depending on the ON and OFF time of the pulses controlling the speed of the motor i.e. The duty cycle of the wave controls its speed. On changing the duty cycle (ON time), we can change the speed. The motor is interfaced to the microcontroller by an IC called motor driver IC i.e., L293D. By interchanging output ports, it will effectively change direction of the motor. The power supply consists of a step down transformer 230/12V, which steps down the voltage to 12V AC. This is converted to DC using a Bridge rectifier. The ripples are removed using a capacitive filter and it is then regulated to +5V using a voltage regulator 7805 which is required for the operation of the microcontroller and other components.

PWM is generated at the output by using program burned into the microcontroller. The program can be written in Assembly language or in Embedded C.

model no: 3A The outline of the project is selection of supply from mains, generator, and inverter and solar automatically by using microcontroller concept. As it is not feasible to provide all 4 different sources of supply, one source with alternate switches are provided to get the same function. In this project we are having 4 switches which we consider as 4 different source of supply. When we press any of the switches it shows the absence of that particular source which is connected to microcontroller as input signals. Here we are using 8051 family microcontroller. The output of microcontroller is given to the ULN2003 this acts as a relay driver. This can drive up to 7 relays. The relays which are used hear are 12V relay. The output can be observed using a fan which is getting uninterrupted power supply from other means if main supply is cut off. The power supply consists of a step down transformer 230/12V, which steps down the voltage to 12V AC. This is converted to DC using a Bridge rectifier.

Model no: 6A The project is based on the principle of firing angle delay of thyristors using back to back SCR’s in series with the load with control being fed from a microcontroller via opto isolators. The firing angle would be adjusted to maintain the load power by rising and decreasing slowly the intensity of the lamp load, resembling the situation of a flasher for aviation obstruction light used in tall buildings. The above operation can also be carried out by using a TRIAC in series with the load. The project is having comparator which is used for ZVR output. The ZVR is given as reference interrupt to microcontroller. The microcontroller is of 8051 family which is of 8bit. In this we are using switch which is used for increasing the firing angle. The optisolator used in the project is used as switching element using this we will trigger the back to back SCR. On the base of SCR triggering the intensity of the AC lamp can be controlled. The power supply consists of a step down transformer 230/12V, which steps down the voltage to 12V AC. This is converted to DC using a Bridge rectifier. The ripples are removed using a capacitive filter and it is then regulated to +5V using a voltage regulator 7805 which is required for the operation of the microcontroller and other components.

Model no: 7 Incandescent lamps exhibit very low resistance in cold condition. Thus at the time of switching from cold state it draws very high current. Thus many lamps fail at the time of switch ON. Engaging two SCR’s in anti parallel or a TRIAC the switching ON time can be precisely controlled by firing after detecting the zero cross point of the waveform of supply voltage. This should result in current waveform rising from zero at the time of switching ON there by increasing the life of lamp. The project is having comparator which is used for ZVS output. The ZVS(ZERO VOLTAGE START ) is given as reference interrupt to microcontroller. The microcontroller is of 8051 family which is of 8bit. In this we are using push button as switch which is used as reference interrupt to microcontroller and using that interrupt we give signal to optoisolator . The optoisolator used in the project is used as switching element using this we will trigger the back to back SCR. On the base of SCR triggering the AC lamp can be controlled to ON at low voltage. The power supply consists of a step down transformer 230/12V, which steps down the voltage to 12V AC. This is converted to DC using a Bridge rectifier. The ripples are removed using a capacitive filter and it is then regulated to +5V using a voltage regulator 7805 which is required for the operation of the microcontroller and other components.

Model no : 11 The outline of the project is to shut down the power supply when it is overloaded. Conventional circuit breaker is based on thermal bimetal lever trip mechanism, which is very slow and the trip time is dependant upon the percentage of overload. So, Electronic circuit breaker is designed which is based on the voltage drop across a series element typically a low value resistor or a CT (current Transformer). The voltage sensed is compared against the preset voltage proportional to the current by a level comparator to generate an output for the Relay or contactor to trip the load. The unit is extremely fast and overcomes the drawback of the thermal type. It uses an 8-bit microcontroller from 8051 family into which program is burned for the operation of this project. The power supply consists of a step down transformer 230/12V, which steps down the voltage to 12V AC. This is converted to DC using a Bridge rectifier. The ripples are removed using a capacitive filter and it is then regulated to +5V using a voltage regulator 7805 which is required for the operation of the microcontroller and other components.
