    AC DIMMER OF TWO LOADS USING SINGLE CONTROLLER

    8,300.00 5,500.00

    This project is intended to attain AC dimmer of two loads using single controller. It is a renowned and aged technique of managing AC power, principally across linear loads for instance heaters brought into play in electric oven.
    In this project, we are using a comparator for zero crossing detection which is fed as an interrupt to the arduino UNO3. Here, the arduino delivers the output based on the interrupt received as the reference for generating triggering pulses. Using these pulses, we drive the Opto-isolators for triggering the TRIAC to achieve integral cycle control as per the input switches interfaced to the arduino. In place of a linear load to be used in the output, a series motor or lamp can be used to verify the output. A lamp is provided in this project in place of a motor for demonstration purpose. The project output with a lamp appears to be a simple project of lamp flickering but the real objective is to verify in a CRO/DSO ,whether at the random switching also the load switches on at zero cross of the waveform or not.

    AC DIMMER TO CONTROL AC VOLTAGE, SPEED OF INDUCTION MOTOR OR HEATER COIL

    4,400.00 3,400.00

    A voltage controller, also called an AC voltage controller or AC regulator is an electronic module based on either thyristors, TRIACs, SCRs or IGBTs, which converts a fixed voltage, fixed frequency alternating current (AC) electrical input supply to obtain variable voltage in output delivered to a resistive load.

    Induction motor speed control is done by varying the frequency of the applied voltage. Raising or lowering the voltage can have some speed control effects but these will be small, difficult to control, load-dependent, possibly cause the motor to overheat and, are not generally recommended.

    ACPWM power control using 555IC and IGBT

    4,100.00 3,200.00

    This project attempts a new speed control technique for the single-phase a.c. induction motor. It presents a design of a low-cost; high-efficiency drive capable of supplying a single-phase a.c. induction motor with a PWM modulated sinusoidal voltage. The circuit operation is controlled by 555 astable multivibrator. The device is aimed at substituting the commonly used triac phase angle control drives. The circuit is capable of supplying a single-phase a.c. induction motor (or general a.c. inductive/resistive load) with varying a.c. voltage.

    Automatic Load Sharing By Parallel Transformer

    6,200.00 4,200.00

    Transformer is basically a static device which transfers the electrical power from one circuit to another circuit with desired change in voltage and current at constant frequency. It is only one device which operates at highest efficiency at full load condition. But abnormal condition occurs at overloading condition which may result in severe problem in future.

    FLEXIBLE AC TRANSMISSION SYSTEM BY STATIC VARIABLE COMPENSATOR

    5,700.00 4,600.00

    In this project to improve power factor of transmission lines using static variable compensator. These were inefficient and because of large rotating parts they got damaged quickly. Static VAR Compensation under FACTS uses TSC (Thyristor Switched Capacitors) based on shunt compensation duly controlled from a programmed microcontroller.
    This proposed system demonstrates power factor compensation using thyristor switched capacitors. The time lag between the zero voltage pulse and zero current pulse duly generated by suitable operational amplifier circuits in comparator mode are fed to two interrupt pins of the 8 bit microcontroller of 8051 family. Prior to the implementation of static variable compensator, power factor compensation was done by large rotating machines such as synchronous condenser or switched capacitor banks.

It is a renowned and aged technique of managing AC power, principally across linear loads for instance heaters brought into play in electric oven. However, the concept of achieving the cycle stealing of voltage waveform by the use of microcontroller can be very precise as per the program written in assembly C language so that the actual time-average voltage or current experienced at the load is proportionately lower than the whole signal if applied to the load.
