Abstract:
A method and a device for controlling a commutation process of a load current between two switching modules are disclosed that each have a MOSFET that can be controlled by a gate-source voltage, and an intrinsic-body inverse diode. To reduce oscillations in the down-commutation of the inverse diodes caused by parasitic circuit parameters, after switching off one of the switching modules, the gate-source control voltage applied to this switching module is temporarily switched off until being increased again the vicinity of the threshold voltage for switching on the MOSFET, before and while the other switching module is switched on, in order to commutate the current from the inverse diode of the one switching module to the MOSFET of the other switching module.

Claim (Index 1):
A method for controlling a commutation process of a load current from a first switching module to a second switching module, wherein the first and the second switching module each comprise a first and a second MOSFET that can be controlled by a gate-source voltage, and that have a first and second intrinsic-body inverse diode, the method comprising:\n applying a first control voltage to the first switching module to switch it off for a first time period, wherein the level of the first control voltage is below a predetermined threshold voltage, above which the first MOSFET becomes minimally conductive, and wherein the time period is selected so that the first inverse diode carries the load current; applying a second control voltage to the first switching module for a second time period to influence the switch-off behavior of the first inverse diode, wherein the second control voltage has an intermediate level between the level of the first control voltage and the level of the threshold voltage, applying a third control voltage to the second switching module for switching it on, wherein the level of the third control voltage is above a predetermined threshold voltage, above which the second MOSFET is minimally conductive, in order to cause a commutation of the load current from the first inverse diode to the second MOSFET; and applying a fourth control voltage with a level below the intermediate level of the second control voltage to the first MOSFET switching module to block it or hold it in the blocking status.
