Abstract
Limited by high-frequency power devices, high-power Wireless Power Transfer (WPT) systems are often required parallel inverters to increase output power. The primary LCC resonant structure has advantages on parallel WPT systems due to its constant current characteristics. But if the topology is not configured properly, the power factor of the inverters will decrease, which will affect the output power and efficiency of the system. This paper analyzes the mechanism of parallel LCC compensation of WPT systems and proposes a parameter configuration method for the problem of excessive source reactive current. The characteristics and imbalance of the topology are studied. The improve results of the configuration method and the imbalance effects are verified through simulations and experiments at different power levels.
