How do generators work? Stu Davies explains…
A generator on a boat is generally powered by an internal combustion engine using an energydense carbon-based fuel such as diesel. Fuel cell generators will be coming to the fore in future years, but are outside our scope for the present.
A generator is basically a rotating magnet inside coils of copper wire. When the magnets rotate, they induce a voltage in the coils of wire. Sophisticated control systems control the output. Simplistically speaking the alternator on our main engine
