VOLTAGE SOURCE ISOLATION IN WIRELESS POWER TRANSFER SYSTEMS
First Claim
1. A wireless power transmitter, comprising:
- a power source;
a first coil connected to the power source;
a second coil connected in series to the first coil; and
a third coil positioned in proximity to the second coil,wherein during operation of the wireless power transmitter;
the power source applies a driving voltage to the first and second coils;
the first coil generates a first magnetic field that transfers power to a receiver resonator;
the second coil generates a second magnetic field that induces a voltage across the third coil; and
the induced voltage across the third coil is applied to a component of the wireless power transmitter.
