Simulation Research on Wireless Power Transmission System Based on IPT

The principles of wireless power transmission and the characteristics of the loosely inductively coupling transformer of MEMS of capsule endoscopy were introduced. After the wireless power transmission system was simulated,the influences of the parameters,such as the gap and ferrite core of the primary and secondary winding,on the loosely coupled transformer inductance and coupling were studied; such as work frequency,the internal resistance of the primary and secondary winding,and the load,on the output power of the system were studied. Finally,some discussions and conclusions were given.
