Three new power take-off (PTO) systems for a wave energy converter (WEC). Influence of PTO parameters on the power capture ratio was studied. WEC with bistable PTO can enhance power capture ratio at low-frequency waves. WECs with coupled (linear or bistable) PTOs expand power capture spectrum bandwidth.
