摘要： An AC-AC converter device includes first and second AC input terminals and first and second AC output terminals. An input device is connected between an input node, a common node, a positive DC terminal and a negative DC terminal, wherein the input node is connected to the first AC input terminal via a first input inductor. An output device is connected between an output node, the positive DC terminal and the negative DC terminal, wherein the output node is connected to the first AC output terminal via an output inductor. A common device is connected between the common node, the positive DC terminal and the negative DC terminal, where the common node is connected to the second AC input terminal via a common inductor. A control device is provided for controlling the switches of the output device and the common device.

摘要： An electric multimode power converter module includes an AC/DC converter, including a first AC port; a DC/AC converter, including a second AC port; a DC/DC converter, including a DC port; a controller; and a communication bus interconnecting the converters. The controller includes a hardware configuration port and sets the module in the following states, based on the value read from the configuration port: a first state in which the module transfers power between the first AC port and the DC port, a second state in which the module transfers power between the DC port and the second AC port, and a third state in which the module transfers power between the AC ports and the DC port. A power supply system includes a shelf device including at least one compartment, and an electric multimode power converter module as mentioned above is inserted in the at least one compartment.
