Transformerless Partial Voltage Architectures to Triple Power Output of xCell Electrochemical Systems

The concept of partial power converter is promising since it might bring significant cost, weight, volume and loss reduction. However, in most cases partial power converters include a transformer to redirect power from one part of the circuit to another. This transformer adds cost, weight, volume and losses and cancels most of the gains promised by the partiality concept. In this paper a TransformerLess Partial Voltage Converter capable of supplying a power up to three times the output power of a standard converter is described and analyzed, its main properties are explained and an example of application is presented.
