Claim Text:
1. A method for switching a cycle in a power transistor circuit having power transistors connected in parallel with one another and including a first power transistor, a second power transistor and at least one third power transistor, which comprises the steps of: specifying a switching time difference of greater than zero between a first switching-on time and a second switching-on time for a first switching cycle; switching on the first power transistor at the first switching-on time; switching on at least two other ones of the power transistors at the second switching-on time; specifying a further switching time difference of greater than zero between a first switching-off time and a second, subsequent switching-off time for the first switching cycle; switching-off of the first power transistor switched on at first and one of the power transistors, which were switched on at the second switching-on time, at the first switching-off time; switching off the other one of the power transistors, which was switched-on at the second switching-on time at the second, subsequent switching-off time; and wherein, in successive switching cycles, the power transistors to be switched at first switching-on times and second switching-off times change cyclically.
