Abstract:
Designed oscillator of quadrature harmonic signals is made on the basis of quasi-conservative managed care with a quick stabilization of output amplitude oscillations. The calculated ratio is tested on a mathematical model in the PSIM-9.03. The use of relay element in combination with a high-speed voltage signal in the feedback allowed us to obtain good performance of the generator under dynamic conditions both at the transition from one frequency to another and at the start-up mode. Designed generator has negligible nonlinear distortions of generated quadrature signals and can be used in multiphase systems of converters, in quadrature modulators and demodulators of communication systems, in frequency multipliers.
Keywords:generator, structural circuit, transfer function, relay element, quadrature signals.
