<p>PROBLEM TO BE SOLVED: To display a function as an AC power source even in a state where two pairs of mutually paired plus side and minus side output terminals are electrically connected at a user side while avoiding the remarkable modification of the increase of the number of parts and circuit constitution in a generator capable of output by changing over DC electric power and AC electric power. SOLUTION: At least one excess current shutdown means 15, 19 is provided between the intermediate part of a first DC coil 1 and the first minus side DC output terminal 16M or between the intermediate part of a second DC coil 2 and a second minus side DC output terminal 20M.</p> |
