Contactless power supply for moving sensors and actuators in high-precision mechatronic systems with long-stroke power transfer capability in x–y plane

An Inductive Power Transfer through metal object

“…There has been several publications like [1], [2], [11], [12], [13], [14] and [15] on power transfer via non-magnetic medium between two coils, whereas power transfer via a ferromagnetic medium is a very new idea and this needs thorough investigations for breakthrough . Examples of contactless power transfers with breakthroughs include contactless energy transfer in hazardous or wet surroundings [11], contactless electric vehicle battery charger [15][16][17], roadway power electric vehicles [18][19][20], robotic applications [21,22],sliding transformers [23] and underwater power transfer [24].…”

“…In [1], Vandevoorde celebrated an inductive link that transferred 20 W of power over a distance of 1 centimetre (cm) with an overall efficiency of 80%. It is justified from [2] that the technology of the Inductive Power or Energy Transfer has also changed dynamically after the increase in the use of (wireless) sensors and actuators. In a number of cases, controlling units and power supplies are separated from the sensors and actuators by metal object or metal compartment (for example, oil pipe).…”

Wirelessly powered ultraviolet light emitting diodes for photocatalytic oxidation

“…The wireless UV-LEDs are powered by resonant inductive coupling (RIC) with a small receiving inductor connected to the UV-LED (receiving circuit) which is inductively coupled to a transmitting inductor, placed around the reactor. A well-known application of RIC is charging of electrical toothbrushes [18], but RIC is thought to be advantageous for many other applications, e.g., biomedical equipment [19], mechatronic systems [20], household electronics, charging batteries of portable devices [21], charging batteries of electrical powered automobiles and busses [22], and sensors.…”

Optimization algorithm and practical implementation for 2-coil wireless power transfer systems

“…Potentially, inductive coupling WPT systems can be used in many industrial applications, such as power supplies for moving sensors and transducers [10], medical implants [11] and wireless electric car charging stations [12] etc. In power industry, due to the importance of High Voltage (HV) cables in the transmission network, on-site condition monitoring is a very important issue [13] [14].…”
