Abstract:
The present invention relates to a method for recharging an energy store (102) used to drive a power semiconductor switch (100), wherein the energy store (102) and the power semiconductor switch (100) are at the same potential, wherein a switching state of the power semiconductor switch (100) is effected by a controller (204, 712), wherein the controller (204) assigns a respective potential value to the energy store (102) at a respective switching state (202) and wherein, by driving at least one charging switch (112, 114, 122, 132, 142, 152), charging of the energy store (102) is activated as soon as the potential value of the energy store (102) corresponds to a ground potential of a supply voltage (106, 216).
