What are the practical disadvantages of using a three-phase Mitkevich rectifier?

Question

Electronics

At work, there is a need to convert several rectifiers to the Mitkevich circuit. The rectifiers are located after three-phase step-down transformers, the well-known Larionov circuit was initially used, the voltage after the rectifier is about 30 volts at a network voltage of 380. After changing to the Mitkevich circuit, the output voltage is about 26 volts, which in this case is a plus (30 volts is a bit too much for a powered scheme). In the original circuit, diodes with very high parameters were used, that is, they do not require replacement when changing the circuit, and the new circuit allows the installation of all three diodes on a common radiator. But in all the reference literature it is written about the shortcomings of the Mitkevich circuit, in particular, the magnetization of the transformer core, The Mitkevich rectifier has a very low utilization factor of the overall power of the transformer and is used at low powers. What is meant by "low power" is not specified anywhere. Transformers with a capacity of 1000 volt-amperes are loaded from about 40 to 80%, depending on the operating mode. Is it possible to apply the Mitkevich scheme in this situation, and what could be the consequences in the long run precisely in connection with the magnetization of the transformer core?
