AC/DC-CONVERTER

摘要

AC/DC convertor to connect to conductors of a multi-phase AC source and a plurality of parallel to each other power factor correction circuitries. There are as many rectifier circuits independent of each other as there are phases of the AC source. Each rectifier circuit has six rectifier elements connected in pairs to the conductors of the AC source and are commonly connected to the output conductors of the rectifier circuit associated therewith forming bridges. There is at least one switch associated with at least one pair of rectifier elements to separate such pair from the conductor of the AC source. Each rectifier circuit is connected to a power factor correction network. Sensors are used for the functional control of both of the phases of the AC source and the one phase power factor correction network. There is a switch control logic connected with such sensors and which based on the signals from the sensors closes or opens the switches of the rectifier network.
