This rotor will be approximately 203mm in diameter or a designated diameter which can be use appropiately for the rotor. Where the rotor’ fins are open we will place an attachable and removeable plastic manufacturer part holding one or two neodimiun magnets. These must be set to allow the magnets when rotating (at a 29” tire at 10mph it will rotate 116 RPMs) to give the coil a gap to allow them to obtain maximum power output. As the coils obtain this power output it will be in an AC mode. It must be converted to a DC mode, then cycled into a PCB board to convert it to either charge a 48V lithium Ion battery (54.6V input) or 52V battery (58.4V input) with max AMP input betwee...

Board will have 6 different isolated 24V DC outputs, these outputs will be able to supply 1A of current typically and 1.2A on burst condition. Also there will be 5V 3A and 3.3V 1A non-isolated outputs. There will be 2x 12V Lead-Acid battery connection for backup the mains input. Power supply will be controlled with an integrated microcontroller and will support security functions. Design will be performed with avoiding obsolete parts and will utilise SMD technology. In the first stage, detailed system plan needed prior to elecrical design.

    we need to design simulink model for transceivers need frequency carriers for up-and down-conversion of the baseband signal. Therefore, a frequency synthesizer is necessary, which increases the complexity and power consumption of the system. IR-UWB, on the other hand, directly modulates the information bits with extremely short-duration pulses. Since the pulse occupies a large bandwidth (no less than 500 MHz), it can be directly emitted without using carriers or any intermediate frequency (IF) processing, greatly reducing the system complexity and the overall power consumption and size [22]. A capsule endoscope communication system includes an inbody transmitter and an on-body receiver with its corresponding blocks for synchronization and base-band processing.

    This project is two fold as you look at the schematic- piezo and metal tank. The suggest is made of placing a second inductor across the primary of the transformer to improve the driver's efficiency . The value of the inductor is empirically picked to minimize power consumption (it offsets some of the capacitance of the piezo transducer. The optimization need to function with any piezo at the 63kHz range Also we consider a push/pull transformer arrangement driven by a similar microprocessor arranged input. This is typical of higher power ultrasonic drivers.
