Intermediate circuit voltage converter, has regulator regulating intermediate circuit voltage such that minimum values of voltage lies straight above permissible minimum value of voltage, where values are caused in operation by power peaks

摘要

The converter has a capacitor module switched parallel to an intermediate circuit capacitor, where the capacitor module is provided for buffering of energy and covering power peaks. Measuring device for determining an intermediate circuit voltage lying over the intermediate circuit capacitor and the capacitor module. A regulator is provided for regulating the intermediate circuit voltage such that minimum values of the voltage lie straight above a permissible minimum value of the voltage, where the minimum values are caused in an operation by the power peaks.
