FORMATION OF SIGNALS OF TASKS WITH THE TRACKING FREQUENCY CONVERTER IN ELECTRIC DRIVE
Keywords:
TRACKING FREQUENCY CONVERTER, TASK, FREQUENCY, MAGNETIC INDUCTION, TRANSFORMER, ENGINEAbstract
Unacceptability of formation of signals of tasks basing on the frequency ω (t) with the following frequency converter under seeming "obvious" formulas α = sin(ωt), b = sin(ωt- 2π/3), с = sin(ωt+ 2π/3) is proved. It is clearly seen on diagrammes of integrals of signals of tasks ∫adt which are proportional to magnetic inductions of loadings (the transformer, the engine). It is offered to replace ωt with φ = ∫ωdt. Further three variants of the decision sin (φ), ωsin (φ) and dω/dt∙sin(φ) + ω2 cos (φ) are investigated.
