  • Patent number: 12012195
    Abstract: An outboard motor includes a power converter to convert AC power generated by a generator that generates power by operation of a drive engine into DC power and to supply converted DC power to a plurality of batteries, a voltage detector to detect a voltage value of the DC power converted by the power converter, and a phase angle controller configured or programmed to perform a retarding/advancing control until the voltage value of the DC power becomes equal to or higher than a first preset voltage value, which is higher than a voltage value at a start of the retarding/advancing control.
    Type: Grant
