  • Control system and method for controlling a rectifier
    Patent number: 9385623
    Abstract: A system and method for controlling a rectifier due to changing operating conditions including at least one reactor per phase connected to the rectifier for providing an input signal, a bias current for controlling the reactor, and a control current for controlling the reactor. The bias current is fixed to a predefined value which is taken as an input signal for providing a control current compensating the difference between the predefined value of the bias current and a start value defining a start point of the linear operating range of the reactor.
    Type: Grant
