The invention relates to the technical field of wireless power transmission, and particularly discloses a WPT system for realizing constant current and constant voltage output based on a variable structure type hybrid topology, the variable structure type hybrid topology is designed, the input ends of a CLC-S type topology and an S-CLC type topology are connected in series, the output ends of the CLC-S type topology and the S-CLC type topology are connected in parallel, and the output ends of the CLC-S type topology and the S-CLC type topology are connected in parallel. The part is a pre-stage circuit and is mainly used for improving the anti-offset performance of the system, on this basis, a variable structure type T-type compensation topology is added to an output end to form a post-stage T-type circuit, and the purpose of constant current/constant voltage switching is achieved by changing the structure of the post-stage T-type circuit. Meanwhile, in order to improve the anti-offset performance of the system, system compensation parameters are designed. Experiments verify that the WPT system for realizing constant-current and constant-voltage output based on the variable-structure hybrid topology provided by the invention can realize constant-current and constant-voltage switching, and has relatively high anti-migration performance in both a constant-voltage mode and a constant-current mode.
