Abstract

A magnetic resonance coupling circuit is a circuit topology (circuit structure) that can achieve high efficiency and high power even in the presence of large air gaps. However, when considering the design of these systems, it is important to achieve both high efficiency and the desired power simultaneously. The desired power refers to the amount of power required by the load on the receiver side. For example, to achieve the maximum efficiency, it is necessary to set the load equal to the optimal load. Consequently, the optimal load determines the amount of power received. Therefore, the amount of power that arrives at the receiver side is not necessarily equal to the desired power. However, if the value of the load is adjusted so that the power becomes equal to the desired power, then the efficiency will not always be equal to the maximum efficiency. In this chapter, we verify these tradeoffs and describe methods to overcome them.
