Abstract
An inductive power transfer OPT system) includes an AC-AC full-bridge converter (Tp1-Tp4) provided between the primary conductive path (Lpt) and an alternating current power supply (Vin). The system may include a controller for controlling the pick-up device to shape the input current drawn from the alternating current power supply (Vin).
Claims23
An inductive power transfer (IPT system) comprising
- a primary conductive path adapted to provide a magnetic field for reception by a pick-up device, and;
- an AC-AC full-bridge converter provided between the primary conductive path and an alternating current power supply to provide a controlled current to the primary conductive path for provision of the magnetic field.
A primary circuit for an IPT system, the primary circuit comprising:
- a primary conductive path adapted to provide a magnetic field for reception by a pick-up device;
- and
- an AC-AC converter provided between the primary conductive path and an alternating current power supply.
A method for controlling an inductive power transfer (IPT) system having an AC-AC full-bridge converter provided between an AC power supply and a primary conductive path, the method comprising:
- controlling a pick-up device of the IPT system to shape an input current drawn from an alternating current power supply.
