A Snubber Circuit With Clamped Energy Feedback for SiC MOSFETs in Hybrid ANPC Converter

IEEE Access
In active neutral-point clamped (ANPC) converters using wide bandgap devices, high switching speeds and inevitable loop parasitics cause voltage overshoot and oscillations during commutation, reducing reliability.

Selective Harmonic Mitigation Technique for High-Power Converters [PDF]

, 2010
In high-power applications, the maximum switching frequency is limited due to thermal losses. This leads to highly distorted output waveforms. In such applications, it is necessary to filter the output waveforms using bulky passive filtering systems. The

Diode-clamped multilevel converters with integrable gate-driver power-supply circuits

, 2009
This paper presents a novel modulation for a two-stage dc-ac power converter with high-frequency isolation installed in a photovoltaic stand-alone system. The presented modulation, which is designed for the converter discontinuous conduction mode of operation, solves the problem of connection to a grid, and permits a bidirectional power flow.
