The Experimental Research of the Capacitor Compensated on the Influence of the Wireless Power Transmission System Performance

The basic constitutions of a Wireless Power Transmission(WPT)system and primary and secondary compensated topologies are introduced.Then,based on a loosely coupling transformer,the WPT system are designed.The results show that the primary compensated in series can reduce the voltage of power supply evidently,the primary comensated in parallel can reduce the current of the primary;the secondary compensated may also reduce the input voltage and primary winding's emission current,compares with the primary compensated,the voltage decline rate is much smaller;both the primary and secondary compensated,the input voltage and the primary current drop,the power factor is increased.But in the situation of SP comensated model,the input voltage is the smallest and the power factor is the highest.
