    • In a forced commutated high power inverter apparatus having a maximum rated output current I Rout , which includes a DC-link capacitor, an anode leakage inductance, a switch arm, a clamp circuitry, and at saturable core unit, the DC-link capacitor has a voltage ripple characterized by a maximum value dV m of an absolute value of a rising rate dV DC /dt, and the anode leakage inductance is connected in series with the DC-link capacitor. The switch arm includes a series connection circuitry of a gate turn-off device and a freewheel diode, and the clamp circuitry includes a clamp capacitor, a clamp diode, and a clamp voltage reset circuitry including a resistor. The saturable core unit has one of linear and gradual saturation characteristics each having a saturation current I sat , which is set so that I Rout > I sat > C 31 x dV m , with a capacitance C 31 of the clamp capacitor.
