Description

technical field [0001] The invention relates to the technical field of AC voltage stabilizers, in particular to a single-phase thyristor AC voltage stabilizer. Background technique [0002] AC voltage stabilizers have been widely used in production and scientific research, and are well known to everyone, and there are various types, but in most cases, the three-phase AC voltage is adjusted and stabilized by using staged and multi-stage fixed voltage compensation. Scheme, the precision of voltage stabilization of this scheme is limited, if higher precision of voltage stabilization is required, the number of compensation series may be more than three levels, which not only makes the control complicated, but also increases the number of compensation transformers, and the weight and structure are huge. Although it can also stabilize the voltage, it is too different from the economical and practical requirements. [0003] Thyristors are also called thyristors. Since its incepti...
