INVERTER SYSTEM AND DRIVING METHOD FOR AN INVERTER SYSTEM

摘要

The present invention provides optimized driving of an inverter device. The inverter of such an inverter device may alternatively be driven in two-level operation or in three-level operation. Through a suitable selection of the driving method, the semiconductor losses in the inverter may be minimized and the thermal loading of the components used may be controlled in a targeted manner. Using the provided operating method for an inverter, more efficient and more protective inverter operation is possible, even at low output voltages and highly inductive or capacitive loading.
