Executive Summary
Difference Between
- Communication System.
- WPT System.
Typical WPT is point – point power transmission.
Famous taper method.
1.Gaussion Taper.
2.Taylor Distribution.
3.Chebychev Distribution.
suppression of side lobe
To increase the power transmission efficiency.
Wireless Power Transmission Optionsfor Space Solar Power
Far Term Space Systems to beam power to Earth
Radio-Wave WPT System
Light-Wave Systems
In a Light wave system highly concentrated solar radiation would be injected into the laser medium (direct solar pumping) and transmitted to earth and converted to electricity by photovoltaic cell’s.
Such system is different from the “classical” SPS using MPT.
Antennas for Microwave Power Transmission
All antennas can be applied for both the MPT system and communication system
We have to use a phased array antenna for the MPT from/to moving Transmitter/receiver.
Generation of Microwave
Need higher efficient generator/amplifier.
Highly efficient beam collection on rectenna array.
Higher stabilized and accurate phase and
Amplitude of microwave when we use phased
array system for the MPT.
Conclusion
Microwave power Transmission is most suitable for a power transmission from moving transmitters to moving target than other transmissions modes.
Accurate Target Detection and High efficient Beam forming By Retro directive system for Solar Power Satellite.
Compatible with other radio services and Application.
Power transmission efficiency of WPT is higher than that other mode in reference to.
Higher efficient generator amplifier
