Summary: | The invention discloses a circuit protection system and method, and an LCC type wireless charging system, and relates to the technical field of circuit protection, and the system comprises a detectionend which is used for being provided for a secondary side controller to detect the voltage outputted by a secondary side output end; wherein the secondary side controller is provided with a signal control end which is connected to the control end of the secondary side rectifier bridge. The technical scheme provided by the invention has the beneficial effects that when the secondary side high-voltage battery pack is disconnected, the field effect transistor in the secondary side rectifier bridge is controlled to keep a conduction state, so that the secondary side enters a non-power output state; when the secondary side high-voltage battery pack and the low-voltage storage battery are disconnected at the same time, the driving power supply of the secondary-side controller is temporarily switched into capacitor powe |
