A connecting element for the releasable sealed connection of a fluid line system to a pressure transducer for detecting positive and negative pressures of a fluid located in the connecting element includes a housing, at least one fluid line connection, and a measuring chamber in the housing. In particular, the present invention is a modulated dc link scheme that dramatically reduces the switching frequency ripple across the PWM output filter inductor and provides cost, size, and weight reductions, as well as efficiency enhancements.
