This paper presents a high-reliability single-phase transformerless grid-connected inverter that utilizes superjunction MOSFETs to achieve high efficiency for photovoltaic applications. The proposed converter utilizes two split ac-coupled inductors that operate separately for positive and negative half grid cycles. This eliminates the shoot-through issue that is encountered by traditional voltage...
In many applications, the query mechanism would co-exist with the data collection at the same time. If these two mechanisms can be combined, the query could utilize some information from the data collection and get benefits on the robustness and stability. We propose a query mechanism which can find the path without any additional beacons or packets and get information from the process of data collection...
