Abstract
Inventia se refera la o metoda de defazare automata cu faza fi = k.360 degree /N, unde k = 0,1 ... N-1, într-o banda îngusta de frecvente si la un circuit defazor cu 120 degree , ca aplicatie a metodei pentru cazul N = 3, k =1. Metoda se bazeaza pe o bucla de reglare automata a fazei, caracterizata prin aceea ca reglarea se face astfel încât sa se mentina un defazaj constant de 0 degree între multiplii de frecventa de ordinul N al semnalului de intrare si semnalul defazat. Defazorul cu 120 degree , realizat cu un circuit de defazare controlat în tensiune (celula cu functia de transfer de tip "trece-jos" si cu TEC, folosit cu rezistenta variabila) utilizeaza doua circuite identice PLL pentru multiplicarea cu 3 a frecventei si fazei semnalelor de intrare si iesire. Semnalul de corectie din detectorul sensibil la faza (de tip "cu 3 stari"), amplificat si integrat, comanda rezistenta dinamica a TEC si astfel defazajul introdus de circuit, în asa fel încât multiplii de frecventa de ordinul 3 ai semnalelor de intrare si iesire sa fie în faza. Domeniul de frecventa în care lucreaza defazorul este limitat de banda de captura a circuitelor PLL. Circuitul nu modifica amplitudinea semnalului la iesire si permite mentinerea unui defazaj constant (120 degree ) între semnalul de intrare si iesire, independent de fluctuatiilefrecventei semnalului sau de variatia parametrilor componentelor cu temperatura sau în timp, eliminând necesitatea reglarii. Circuitul de defazare cu 120 degree poate fi utilizat în cadrul unor aparate care masoara cu precizie componentele simetrice de tensiune si curent într-un sistem trifazat de marimi sinusoidale nesimetrice, dThe invention relates to an automatic phase-shifting method with the phase fi = k.360 degree / N, where k = 0.1 ... N-1, in a narrow frequency band and a 120 degree phase shunt circuit, as application of the method for the case N = 3, k = 1. The method is based on an automatic phase adjustment loop, characterized in that the adjustment is made in such a way as to maintain a constant degree of 0 degrees between the input N-frequency multiples of the input signal and the phase signal. The 120 degree shunt with a voltage controlled phase switching cell (low pass and TEC) uses two identical PLL circuits to multiply the frequency and phase of the signals in and out. Corrective signal from the step-sensitive (3-state-type) detector, amplified and integrated, controls the dynamic resistance of the TEC and thus the phase input introduced by the circuit, so that the 3-way frequency of the input and output signals to be in phase. The frequency range in which the phasing is working is limited by the capture band of the PLL circuits. The circuit does not change the output signal amplitude and maintains a constant (120 degree) phase shift between input and output signal, independent of signal frequency fluctuations or component temperature variations with temperature or time, eliminating the need for tuning. The 120 degree downstream circuit can be used in devices that accurately measure the symmetrical voltage and current components in a three-phase, unimetric sinusoidal
