For example: the Uab is Ucd AC _120V, the two AC currents can output AC of AC _120V specification independently or in parallel, and the two AC currents can output AC of AC _240V specification after being connected in series. Therefore, the free switching of the alternating currents of the two specifications is realized.
For example: the two paths of alternating current are connected in parallel and then can output alternating current with the specification of AC _120V _10KW, and the two paths of alternating current are connected in series and then can output alternating current with the specification of AC _240V _5KW, so that high-power output is realized.
