Description
Technical Field
The present application relates to the field of medical devices, and in particular, to a transmitting electrode for electric field coupling energy transfer.
Background
Electric-field-coupled power transfer (ECPT), a technique for achieving power transfer using a coupling capacitance between a transmitting electrode and a receiving electrode. Typically in the form of dual transmit electrodes, dual receive electrodes. Coupling capacitance, also known as electric field coupling or electrostatic coupling, is a coupling mode due to the presence of distributed capacitance. The coupling capacitor enables the strong current system and the weak current system to be coupled and isolated through the capacitor, provides a high-frequency signal path, prevents low-frequency current from entering the weak current system, and ensures personal safety. Besides the functions, the coupling capacitor with the voltage extraction device can also extract power frequency voltage for protection and reclosing, and plays a role of a voltage transformer.
For the four-electrode model, when the electrode size is limited and a sufficient equivalent capacitance value cannot be achieved (the substrate area is too small or the substrate spacing is too large), if the system resonant frequency is set to a required frequency, a larger inductor is generally required for reactive power compensation. However, excessive inductance is typically accompanied by a large series equivalent resistance and a large volume. The former reduces the system transmission efficiency and the latter generally fails to meet the device volume requirements. In general, a resonance capacitor is added between two transmitting electrodes, the resonance state of the system is affected by the position change of the polar plate, especially when the system is applied to medical instruments implanted in human bodies, the polar plate has smaller area, the distance can also be changed due to the posture change of patients, and therefore, the resonance frequency can also be changed.
