This circuit also gives light indication of any fault that occurs in the control circuit. Its intensity cannot be controlled according to the requirement, so there is a need to switch to an alternative method of lighting system, i. A cluster of LEDs is used to form a street light. The speed control of the DC motor is achieved by varying the duty cycles PWM Pulses from the microcontroller as per the program. Now, if a voltage is applied among the drain and source the current flows freely between the source and drain and the gate voltage controls the electrons in the channel.

For better understanding of this concept, here we have explained some projects. He has 8 years of experience in Customer Support, Operations and Administration. The speed control of the DC motor is achieved by varying the duty cycles PWM Pulses from the microcontroller as per the program. The main concept of this project is to develop a circuit that delivers the output approximately triple to that of the input voltage by Marx generator principle. In the present system, mostly the lightning-up of highways is done through High Intensity Discharge lamps HIDwhose energy consumption is high and there is no specialized mechanism to turn on the Highway light in the evening and switch off in the morning.

A cluster of LEDs is used to form a street light. Therefore, the motor remains in an operational state or restarted to operate at the same speed as before by using stored data from an EEPROM.

If the power supply is interrupted, the EEPROM retains that information to mard the motor at the same speed as before while the power supply was available. When we apply the negative voltage to gate, the electrons present under the oxide layer through pushed downward into the substrate with a repulsive force. This system is built to overcome the present day, drawback of HID lamps. This project is designed to control the lights automatically on the highways using microprocessor by variants of the clock pulses.

When there is zero moefet on the gate terminal, the channel shows its maximum conductance.

More voltage applied on the gate terminal, the device has good conductivity. Many of electronic projects developed using MOSFET such as light intensity control, motor control and max generator applications. The deflection region is populated by the bound negative charges which are allied with the acceptor atoms.

The oxide layer presents among the source and drain terminal. The deflection region populates by the bound positive charges which are allied with the donor atoms. Now-a-days most of lights placed on the highways are misfet through High Intensity Discharge lamps HIDwhose energy consumption is high. The applications of the MOSFET used in various electrical and electronic projects which are designed by using various electrical and electronic components. As the voltage on the gate is negative or positive, then decreases the channel conductivity.

This method overcomes the old technique SPWM to control an AC motor that has high-harmonic distortion due to the asymmetrical nature of the PWM mosfer characteristics.

The process thus repeats.

The channel width is controlled by the voltage on an electrode is called gate which is located between the source and drain. It is designed to generate high-voltage pulses using a number of capacitors in parallel to moseft during the on time, and then connected in series to develop a higher voltage during the off period.

This circuit also gives light indication of any fault that occurs in the control circuit. The microcontroller contains programmable instructions that controls the intensity of lights based on the PWM Pulse width modulation signals generated. Now, if a voltage is applied among the drain and source the current flows freely between the source and drain and the gate voltage controls the electrons in the channel.

This project is enhanced to control the speed of the BLDC motor by varying the duty cycle. When there is no voltage on the gate terminal the device does not conduct. Its resistance reduces drastically according to the daylight, which forms as an input signal to the controller.

The Space Vector PWM is a sophisticated technique for controlling Mossfet motors by generating a fundamental sine wave that provides a pure voltage to the motor with lower total harmonic distortion. It can be set from p-type to n-type by applying positive or negative gate voltages respectively. The MOSFET is an important element in embedded system design which is used to control the loads as per the requirement.

When we apply the positive gate voltage the holes present under the oxide layer pushed downward into the substrate with a repulsive force. The main intention of this project is to operate a BLDC motor at a particular speed with a predefined voltage. Its intensity cannot be controlled according to the requirement, so there is a need to switch to an alternative method of lighting system, i.
