Abstract
A method for switching a cycle in a power transistor circuit is created, especially in a parallel circuit of power transistors. The method includes the step of specifying a switching time difference and the switching of the power transistors of two switching times which are separate from one another by use of the switching time difference.

A method for switching a cycle in a power transistor circuit having a first power transistor and a second power transistor connected in parallel with the first power transistor, which comprises the steps of:
- specifying a first switching time difference of greater than zero between a first switching time of a predetermined type and a second switching time of the predetermined type for a first switching cycle, the predetermined type being selected from a group consisting of a switching-on time and a switching-off time;
- switching the first power transistor at the first switching time;
- and
- switching the second power transistor at the second switching time.
A control unit for switching a power transistor circuit having a first power transistor and a second power transistor connected in parallel with the first power transistor, the control unit programmed to:
- specify a first switching time difference of greater than zero between a first switching time of a predetermined type and a second switching time of the predetermined type for a first switching cycle, the predetermined type being selected from a group consisting of a switching-on time and a switching-off time;
- switch the first power transistor at the first switching time;
- and
- switch the second power transistor at the second switching time.
A switching device, comprising:
- a power transistor circuit having first and second power transistors connected in parallel with one another;
- a control unit for switching said power transistor circuit, said control unit programmed to:
- specify a first switching time difference of greater than zero between a first switching time of a predetermined type and a second switching time of the predetermined type for a first switching cycle, the predetermined type being selected from a group consisting of a switching-on time and a switching-off time;
- switch said first power transistor at the first switching time;
- and
- switch said second power transistor at the second switching time.
