**2. Basic resonant coupling techniques**

There are four basic configurations of the primary and secondary side of the WPT system to realize resonant compensation of the leakage inductance [16–18]. This chapter focuses on investigating the properties of possible compensation methods, which include serial-serial, serial-parallel, parallel-serial, parallel–parallel.

*Circuit parameters for the evaluation of compensation techniques.*

The analysis of individual configurations is further provided, while and examples of characteristics derivations are based on the circuit parameters listed in **Table 1**.
