Method for protecting power semiconductors of a converter and a power converter

The active clamping control method involves using at least one power interrupter connected to a clamping device with a voltage threshold, preferably connected between the power terminal and the control of interrupter. In this way the maintenance of maximum allowable voltage at the interrupter poles...

More Information
Summary:The active clamping control method involves using at least one power interrupter connected to a clamping device with a voltage threshold, preferably connected between the power terminal and the control of interrupter. In this way the maintenance of maximum allowable voltage at the interrupter poles is ensured, by inhibiting the clamping function when the interrupter is off. The mechanism for maintaining the maximum allowable voltage includes an inhibition interrupter connected between the clamping device and the control of power interrupter. Independent claims are included for an active control device.
