WIRELESS POWER TRANSMITTER INCLUDING MINIATURIZED INVERTER FOR REDUCING HARMONICS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17956443 titled 'WIRELESS POWER TRANSMITTER INCLUDING MINIATURIZED INVERTER FOR REDUCING HARMONICS
Simplified Explanation
The abstract describes a wireless power transmitter that includes various components such as a transistor, capacitors, inductors, and coils. These components work together to amplify an input signal and transmit power wirelessly.
- The wireless power transmitter includes a transistor that amplifies an input signal and a driving voltage.
- A first capacitor is connected in parallel with the transistor.
- A first LC resonant circuit, consisting of a first inductor and a second capacitor, is also connected in parallel with the transistor.
- A third capacitor is connected to the output terminal of the transistor and the first LC resonant circuit.
- A feeding coil is connected in series with the third capacitor and forms a second LC resonant circuit.
- A transmission resonator, consisting of a transmission coil and a fourth capacitor, is connected in series.
- The transmission coil is magnetically coupled with the feeding coil, allowing power received from the feeding coil to be output through the transmission resonator.
