Determining the Parameters of the Sine-Wave Filter Factors Affecting Filtration Quality

Abstract

: The paper deals with proposals for the procedure of selecting the parameters of the sinewave filter in case of increased voltage frequency (400 — 600 Hz) on the output of frequency converter, which is an element of power supply system. Author describes in article the structure of the power supply system for an unmanned underwater vehicle, which contains a sine-wave filter connected to frequency converter output. The system ’s simulator has a block structure. As blocks previously developed computer models of electrical devices (transformer, autonomous voltage inverter, L-shaped filter, rectifier) are used. The subject of sine-wave filter output voltage quality and contribution to this of input voltage’s modulation index is also described at 100 — 200 Hz.
