  • Current converter apparatus having a multi-phase current converter
    Patent number: 9717164
    Abstract: A current converter apparatus includes a multi-phase current converter having current-converter modules for each phase that are electrically connected to one another and arranged in a current-converter cabinet. Each current-converter module has at least one semiconductor component arranged on a heat sink and includes just two semiconductor components connected to each other and connected to be controlled by a control component. The current-converter modules in the current-converter cabinet are arranged so that the current-converter modules of each current-converter phase form a horizontal row of modules arranged one beside the other and the rows are arranged vertically one above the other.
