Wireless Power Transfer Basics in Brief
- 1. A Brief Basics on Wireless Power Transfer (WPT) Dipra Paul BSc. In EEE AUST, Bangladesh MSc(ongoing) UNIST, Rep. of Korea.
- 2. Introduction Mechanism Transmission Frequencies Rectenna and operating frequencies Advantages Disadvantages
- 3. Transmission of power/electrical energy without the need for a physical connection/link Wireless power transfer is useful to power electrical devices where interconnecting wires are inconvenient, hazardous, or are not possible. Introduction:
- 4. Non Radiative/ Near Field: Magnetic coupling/ Inductive coupling Electric field coupling/ Capacitive coupling Magnetic coupled Resonance Radiative/ Far field: Radio Frequency Leaser Beams
- 5. To realize WPT let’s consider MPT mechanisms Transfer of power through space by means of microwaves Converts DC power to microwaves Transmits microwave radiation to a target Target converts the Microwave radiation back to DC power WPT Mechanism:
- 6. Transmission Frequency: 2.45 GHz 5.8 GHz 8.5 GHz 10 GHz 35 GHz 2.45 GHz is the most efficient frequency to transmit microwaves.
- 7. Reception Antenna type and operating frequency: Printed Diplomo (2.45GHz) Circular patch (2.45GHz) Printed Dual rhombic (5.6GHz) Square Patch (8.51GHz) A receiver has to receive and convert the microwaves back to DC. The device is known as Rectenna which includes an antenna coupled with a rectifying circuit.
- 8. Can get rid of cables Safe to use Ease of Use No plugging needed Low Transmission Losses Efficient Advantages:
- 9. Interference –EMI, EMS. Capital cost for practical implementation is very high Security Issues Rectenna Size Disadvantages:
