Abstract
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.
Claims12
A method for driving an inverter (1) having at least two different operating modes, the method comprising:
- driving the inverter (1) in a two-level operation in a first operating mode;
- and
- driving the inverter (1) in a three-level operation in a second operating mode.
An inverter system, comprising:
- an inverter (1) configured to output an AC voltage;
- and
- a control device (2) configured to drive the inverter (1) in a two-level operation in a first operating mode and to drive the inverter (2) in a three-level operation a second operating mode.
