This application provides a converting circuit and a charging apparatus, and relates to the field of electronic technologies. The converting circuit includes two groups of parallel connected primary-side converting circuits, two groups of parallel connected secondary-side converting circuits, a third secondary-side converting circuit, a first transformer, a second transformer, and a third transformer. The two groups of parallel connected primary-side converting circuits are connected in a one-to-one correspondence with a primary side of the first transformer and a primary side of the second transformer. The two groups of parallel connected secondary-side converting circuits are connected in a one-to-one correspondence with a secondary side of the first transformer and a secondary side of the second transformer. The two groups of parallel connected primary -side converting circuits include a first input end and a second input end, or the two groups of parallel connected secondary -side converting circuits include a first input end and a second input end. The first input end and the second input end are separately connected to a primary side of the third transformer. Therefore, a primary-side converting circuit does not need to be disposed for the third transformer, to effectively reduce circuit complexity and reduce the circuit costs.
