Focusing on the raft-type wave power generation device, the influence of response time constant, nominal latching damping coefficient, power capture damping of power generation system on the efficiency of latching control is investigated. The results show that the time constant has an effect on the latching control, and the smaller the constant time, the larger the power captured by the device. As the ratio of nominal latching damping to power capture damping increases, the latching control approaches the absolute latching control, and the ratio of power captured by the device with latching control to that without latching control increases. The optimal power capture damping corresponding to the peak captured power decreases due to the latching control, and the power capture ability of the device with optimal power capture damping can be further improved by latching control. Besides the ratio of power captured by the device with latching control to that without latching control increases and then decreases as wave period increases.
