Static frequency converter which compensates for fluctuations in a voltage source while controlling the waveform applied to a charge while controlling the waveform applied to a charge |
摘要 |
The static frequency converter controlled by a control parameter processing and command generation element includes an active filter at the terminals of a dc/dc converter powering a load, wherein the active filter includes an inductance (L1) in series with a diode (D1) grounded through a condenser (C0) and a switch (K5) controlled by the control parameter processing and command generation element and that the dc/dc converter includes at least one complete bridge, one of the arms of which has two condensers (C1,C2) and the other arm has four switches (K1. . . K4). This converter can be used with all load types that can be controlled by frequency converters, and more particularly to a transformer type inductive load or alternating electric motors, with or without commutators, and particularly to single phase and multiphase asynchronous motors.
