  • Abstract
    In this paper, a universal voltage clamping circuit for the T-type neutral-point-clamped (TNPC) converter is introduced. It is shown that, for any TNPC implementation, the proposed voltage clamping circuit can well suppress all voltage spikes of power devices at the switching transients. Therefore, the devices can operate in a much safer region.
