Half wave rectifier project pdf

This project is designed to develop as a robotic vehicle that can be controlled by a cell phones. DTMF commands from a phone send to another cell phone which is mounted on the robotic vehicle. These commands are fed to a PIC microcontroller of 8-bit architecture to operate the vehicle movement through motor interface. Conventionally Wireless-controlled Robots Use Rf Circuits, Which Have Limited Working Range, Limited Frequency Range and Limited Control. Use of a Mobile Phone for Robotic Control Can Overcome These Limitations. It Provides the Advantage of Robust Control, Working Range as Large as the Area of the Service Provider, No Interference with Other Controllers. Although the Appearance and Capabilities of Robot Vary Vastly, All Robots Share Feature of a Mechanical, Movable Structure Under Some Form of Control. The Control of Robot Involves Three Distinct Phases: Perception, Processing and Action. Generally, the Preceptors Are Sensors Mounted on the Robot, Processing is Done by the On-board Microcontroller or Processor, and the Task is Performed Using Motors or with Some Other Actuators. In This Project the Robot is Connected to Gsm mobile (using DTMF technology) Which is Controlled by User Mobile Phone. With the Help of Commands We Can Move Our Robot in Desired Direction as Per Our Requirement. COMPONENT USED: * DTMF DECODER * 8-BIT PIC MICROCONTROLLER * CELL PHONES * DIODES * BATTERY(6-VOLT) * DC MOTOR * WHEELS ETC. Project By Abhi Sharma.

The conversion of AC into DC is called Rectification. Electronic devices can convert AC power into DC power with high efficiency. During the positive half cycle, the diode is forward biased and it conducts and hence a current flow through the load resistor. During the negative half cycle, the diode is reverse biased and it is equivalent to an open circuit, hence the current through the load resistance is zero. Thus the diode conducts only for one half cycle and results in half wave rectification. The input and output voltage waveform may be analytically written as: .
