| 摘要 |
The circuit has a sub-module (11) whose input side comprises a single-phase half bridge (20), where a load-side of the sub-module includes a single-phase full bridge (21). A supply module stores or supplies electrical power. An input side of the supply module is provided with the single-phase half bridge. An intermediate circuit capacitor (22) and a power converter (40) i.e. direct voltage current converter, are connected parallel to each other via an intermediate circuit (25) at a direct voltage-side of the module. A supplementary electrical power source is connected to the power converter. The supplementary power source is designed as an electrical energy storage (46) e.g. double layer capacitor or booster battery, and an external power supply source e.g. photovoltaic unit, fuel cell, generator, electrical supply network or power supply unit. An independent claim is also included for a vehicle drive. |
