Patent
Three-phase inverter arrangement
TL;DR: In this article, an inverter arrangement for generating a three-phase AC output voltage is provided with three pulse-controlled, free-running single-phase inverters, connected at their inputs to a DC voltage source, and at their outputs to respective low-pass filters.
Patent
Apparatus for determining the phase difference between the rolling oscillation of a ship and a liquid contained in a stabilizing tank
TL;DR: In this article, the measured rolling rate of a ship and a measured liquid level difference in a liquid contained in a stabilizing tank are supplied to frequency dependent members having identical frequency response to obtain a derived roll angle and derived level difference after which a circuit is provided to measure the phase difference between the quantities developed and to develop an output analog voltage representing the difference between a desired relationship between the phases of the two and the actual phase relationship.
