| Summary: | This research presents a wireless DC-to-DC power transfer over
a short distance. Distance of remotely located target from the source coil
and received voltage at the load are the major concern in the Wireless
Power Transfer (WPT) applications. The inversely proportional behavior
of these parameters degrades the system performance. In order to optimize
these values and achieving transfer efficiency, microelectronic circuit is
developed and simulated using NI Multisim. The transmitter and receiver
modules are constructed and their individual blocks are simulated and
analyzed for wireless power transfer. Two inductively coupled coils are
designed and used in both transmitter and receiver sections. The inverter
is designed using H-bridge with five CMOSFET (IRF520NS, IRF5210S)
and its gate signal is generated using NE555 timer IC with two output clock
signal where one was inverted using an NMOS inverter. Through
simulation, it is observed that with such a design, the power transfer has a
limited range, and the range will be smaller for smaller receiving coils and
improper alignment. A simulated model is proposed and implemented in
this paper. The simulation outputs of each unit is plotted and analyzed
separately. In addition, transient plot of load resistance versus output
voltage are illustrated to analyze the power of dc-dc power transfer circuit.
It is observed that the output voltage is increased correspondingly with
increasing load resistance and determined good output voltage is harvested
with the optimized load resistance is at 1 kΩ and is 4.25 V. Simulated
results shows that the proposed system can transfer power with high
efficiency. This proposed system could be made commercially viable
through further research work. |
