| 摘要 |
The invention relates to a method for operating an inverter (W) comprising a step-up device (H) which is upstream-connected by means of an intermediate circuit and is connectable to a direct-current source (G) with a variable reference sampling current (Ireference), wherein said inverter (W) and the step-up device (H) are provided with an efficiency optimising working area, respectively. When the variable reference sampling current (Ireference) is raised and the step-up device (H) approaches a pulse duty factor value (T), the intermediate circuit voltage (UDCW) is reduced and the variable reference sampling current (Ireference) is stabilised, said intermediate circuit voltage (UDCW) is reraised. When the direct-current source (G) is in a permanent operational state, the inverter (W) and the step-up device (H) operate in the efficiency optimising working area thereof, respectively. |
