Abstract: A serial-parallel converter protection system includes a controller, a drive, a first switching transistor, and a second switching transistor. An input terminal of a converter is connected to an output terminal of the converter through the first switching transistor. The output terminal of the converter is connected in parallel with the second switching transistor.
