DIGITAL GENERATOR OF THREE-PHASE SINUSOIDAL SIGNALS

摘要

Usage: in electrical measurement technique, particularly in the motor control system. SUMMARY OF THE INVENTION: three phase digital sinusoidal signal generator comprises a control signal generator, which performs the function of the control unit controlled by a variable frequency oscillator, a reversible counter, blocks permanent storage, tsifroanalogoeye converters, the exclusive OR. controllable reference voltage source, the amplitude correction unit. The purpose of the invention - reduction of harmonic distortion of output signals - is achieved through the use of mathematical transformation vectors results from the initial rotating rectangular coordinate system fixed in a symmetrical three-phase system 4 yl.
