ABSTRACT:
A three-level inverter, in which the upper and lower half of each phase relieves the semiconductor switching elements from excessive values of the rate of rise of the recurring positive forward blocking voltage. This is done with a circuit arrangement in each half has a wiring diode, a switching off relief capacitor, a further wiring diode, a storage capacitor and a discharging resistor serving as the d-c load. Additional energy feedback devices feed back, into the supplying d-c voltage source, energy which is produced in the switching-off process and is temporarily stored in the circuitry.
