CHARGING DEVICE

摘要

Charging device (1) includes a transformer (10) that is equipped with two input windings (10a, 10b) provided to correspond to connection terminals (4, 5) of at least two input power sources (2, 3), together with a charging output winding (10c) to output charging power voltage by being electromagnetically coupled to the input windings (10a, 10b), as well as an auxiliary output winding (10d) to output an electric circuit power voltage; a first switching element (11) and a second switching element (12) electrically connected respectively to input windings (10a, 10b); and a switching control circuit (13) to mutually control the first and second switching elements (11, 12).
