摘要： A multi-module bidirectional power converter may comprise a low side common node, a high side common node and at least first and second bidirectional DC/DC converter modules. The modules may comprise first and second low voltage switches, first and second high voltage switches and a transformer. The transformer may comprise a low side winding having first and second legs and a high side winding having first and second legs. The first leg of the low side winding may be connected with the first and second low voltage switches of the module. The second leg of the low side winding may be connected with the low side common node of the multi-module bidirectional power converter. The first leg of the high side winding may be connected with the first and second high voltage switches of the module. The second leg of the high side winding may be connected to the high side common node of the multi-module bidirectional power converter. Such an arrangement may provide operability of the multi-module bidirectional power converter with any one or more of the modules so that efficiency is maintained when electrical loads are high and so that Zero Voltage Switching is maintained when electrical loads are low.
