Abstract

The performance of modern wide bandgap semiconductors cannot be fully exploited in inverters for motor drive applications, since faster switching is not possible due to the high du/dt causing overvoltages due to reflections on cables and EMI issues. Classical LC filters are also not suitable, as these limit power density. This situation calls for an active du/dt filter implementing intelligent switching transitions of the power semiconductors to ensure high efficiency and low du/dt at the output simultaneously. Theoretically, the modulation scheme can deliver ideal smooth transitions. However, in practical setups non-idealities cause severe oscillations of the resonant tank. This paper studies the origin of this oscillation and proposes a compensation method to successfully reduce the undesired oscillation.
