  • High-power AC voltage stabilizer
    Patent number: 4286207
    Abstract: An injection transformer has a primary winding series connected with a pair of inverse parallel-connected thyristors between a pair of input terminals. A control circuit is connected across a pair of output terminals for firing the thyristors. The injection transformer has a secondary winding connected between one of the input terminals and one of the output terminals for producing an injection voltage. A filter has components presenting a high impedance to the harmonic frequencies of the injection voltage and a low impedance to the fundamental frequency of the injection voltage, and has components presenting a high impedance to the fundamental frequency of the injection voltage and a low impedance to the harmonic frequencies of the injection voltage.
