Abstract

The invention discloses a wireless power supply device for testing guided missiles. The wireless power supply device comprises a transmitter and a receiver, wherein the transmitter comprises a transmitting coil used for transmitting an electromagnetic wave signal, a first alternating-current voltage source used for providing first voltages for the transmitting coil, and a partial pressure unit used for adjusting the sizes of the first voltages at the two ends of the transmitting coil. One end of the first alternating-current voltage source is electrically connected with one end of the transmitting coil through the partial pressure unit, and the other end of the first alternating-current voltage source is electrically connected with the other end of the transmitting coil. The receiver comprises a receiving coil used for receiving the electromagnetic wave signal from the transmitting coil, and a rectifying unit used for converting second voltages at the two ends of the receiving coil into third voltages required by loads, the two ends of the receiving coil are electrically connected with the input end of the rectifying unit, and the output end of the rectifying unit is electrically connected with the loads. The reliability of the wireless power supply device is remarkably improved, and the wireless power supply device is beneficial to achieving miniaturization of the power supply device.

Description

technical field [0001] The invention relates to the technical field of power supply devices, in particular to a wireless power supply device for missile testing. Background technique [0002] Missile testing is very important to missile production, and missile testing runs through all aspects of missile production design, use and storage. As we all know, in the process of wireless communication, electromagnetic waves carry energy. Electromagnetic waves of a specific frequency can cause objects to vibrate, and two objects with the same natural frequency can transmit this vibration, thereby being able to transfer energy. [0003] Wireless power transfers energy through the air using a very low-strength magnetic field. This magnetic field is similar to the Earth's magnetic field, but the difference is that the wireless power supply uses an oscillating magnetic field, while the Earth's magnetic field is a static magnetic field. Simply put, wireless power supply uses resonance...
