Abstract
Due to the high energy consumption in data and telco centers, the use of 380V or 400V DC facility-level
distribution has been proposed as an alternative to the conventional AC distribution for a more efficient
power delivery structure. The DC voltage is powered from the three-phase mains by a PFC rectifier
and in many cases a mains transformer is used to provide galvanic isolation. In order to achieve a high
efficiency in the DC voltage generation and to implement the required isolation, a single-stage concept,
such as a matrix-type rectifier that enables PFC functionality and galvanic isolation in a single conversion,
can be beneficial. In addition, due to the fact that with the matrix-type rectifier the galvanic isolation is
performed with a high-frequency transformer, this results in a more compact rectifier system compared to
conventional systems where the mains-frequency isolation transformer is located at the input of the PFC
rectifier.
In this paper, an overview of isolated matrix-type PFC rectifier topologies is given and a new converter
circuit is proposed, analyzed and comparatively evaluated against another promising PFC rectifier concept,
the phase-modular IMY-rectifier.
