System and method for providing simple feedback signals indicating if more or less power is required during inductive power transmission

摘要

An inductive power outlet for providing power to an electric load via an inductive power receiver includes at least one primary inductive coil wired to a power supply via a driver configured to provide a driving voltage across the primary inductive coil such that a secondary voltage is induced in a secondary inductive coil associated with the inductive power receiver. The driver may include a controller configured to receive feedback control signals from the inductive power receiver indicating if more or less power is required. The controller may be further configured to adjust the driving voltage according to the control signals.

1. A method for regulating inductive power transmission from an inductive power outlet to an inductive power receiver, the inductive power outlet including a primary inductive coil wired to a power supply via a driver, and the inductive power receiver including a secondary inductive coil wired to an electric load, the method comprising:
providing a driving voltage to the primary inductive coil thereby; inducing a secondary voltage in the secondary inductive coil; the driver receiving simple feedback control signals from the inductive power receiver; and the driver responding to the simple feedback control signals by: increasing power by a predefined incremental value when the received feedback control signal is of a first type, and reducing power by a predefined incremental value when the received feedback control signal is of a second type.
