Problems solved by technology

However, if this method is to improve the voltage stabilization range and accuracy, a large number of taps need to be set on the autotransformer, and each tap needs to be connected to multiple thyristor switches at the same time. In the process of making the voltage stabilizer, the taps are difficult to handle. , so this method is only suitable for places that do not require high precision of voltage regulation
