DUAL MODE DC-DC CONVERTER AND METHOD OF OPERATING A DUAL MODE DC-DC CONVERTER

摘要

In a method of operating a dual mode DC-DC converter having first and second bridge converters connected via a transformer, a capacitor in series with each winding of the transformer, and an inductance, wherein each bridge converter includes a number of switches operating under the control of a controller, in a first mode of operation, the switching of the number of switches is controlled in a manner to transfer DC electrical power from the first bridge converter to the second bridge converter, or vice versa. In a second mode of operation, one switch of each bridge converter is maintained in a closed state and one switch of each bridge converter is maintained in an open state while the switching of the other of the number of switches of the first and second bridge converters is controlled in a manner to transfer DC electrical power from the first bridge converter to the second bridge converter, or vice versa.
