Teaching experimental device of magnetic coupling resonant wireless power transmission

The utility model provides a teaching experimental device of electromagnetic hybrid magnetic suspension. A transmitting circuit coil bracket is fixed on an experimental bedplate of the device and is provided with a transmitting circuit coil. The experimental bedplate is provided with a guide rail which is slidingly provided with a receiving circuit coil bracket which is provided with a receiving circuit coil. The transmitting circuit coil is connected between two ends of a capacitor C1 through wires to form a transmitting circuit. One end of the capacitor C1 is also connected to the cathode of a DC power supply E. One end of the capacitor C1 is also connected to a resistor R3. The anode of the DC power supply E is connected to the drain electrode of a field effect switch tube P through a shunt resistor R1. The gate electrode of the field effect switch tube P is respectively connected to a resistor R2 and the resistor R3. The resistor R2 is connected to the output end of an oscillation circuit. The source electrode of the field effect switch tube P is grounded. Two ends of the capacitor C2 are also connected to a load such as a high brightness light-emitting diode or a small lamp. The teaching experimental device has the advantages of simple structure, reasonable design and high practicability and convenience, and the smooth development of an experimental course is facilitated.
