There are two types of electric current in daily use: direct current and alternating current. The alternating current is much more widely used because it is more flexible to use. However, alternating current cannot be stored, it should be used as it is produced. The advantage of direct current is that it can be stored in accumulators. Rectifiers are devices that convert alternating current into direct current.
Traditional rectifiers include a technology using Thyristor controlled structure with isolation transformer. Its advantage is that it is resistant to harsh conditions, and its disadvantage is that it pollutes the network due to the harmonic currents it draws. There are 12-pulse, 18-pulse, or even 24-pulse variants to reduce harmonic distortion.
Modular rectifiers, new technologies operating at high frequencies to prevent harmonic distortion and increase efficiency have come into the field of application. The advantage of this technology is that it allows to connect many rectifiers in parallel with current sharing. Thus, the user can create redundant systems with very little cost and is not affected by any module failure, and can upgrade the defective module to the first day's security level without turning off the rectifier and without leaving the load without power.
