It presents a cascaded H-bridge multilevel inverter employing bidirectional switches to design an effective circuit to increase the number of output voltage levels. In the proposed circuit configuration, each inverter produces five output voltage levels. Because the output terminals of both inverters are connected in series, the final output voltage becomes nine levels including a zero. Different...
In this paper, a new fault tolerant inverter design is presented, with N+k redundancy and hot-swapping capability. The proposed method uses N+k parallel H- bridges capable of fault detection and isolation. An open collector "fault" signal can be set or control each bridge. A flexible control unit accepts, activates or deactivates the "fault" signals of all the H-bridges. A prototype...
