Abstract：To eliminate the leakage current of single-phase non-isolated photovoltaic inverter，a six-switchphotovoltaic inverter topology with low leakage current was proposed. The topology consists of a voltage multipliercircuit，a common ground three-level inverter circuit and a LC output filter circuit. The combinat...

Abstract：Under the planned system，the fixed price makes it difficult to encourage hydropower to participatein regulation，and the complex hydraulic constraints lead to difficulties in hydropower spot market clearing. Toencourage hydropower to participate in regulation through spot-price incentives and enrich its reve...

YANG He，CHEN Zhaoyu，ZHANG Jinhua，XU Jing，WANG Jingpeng，ZHU Shichang
Abstract：In response to the issues of large volume，high cost，and complex control algorithms associated withvoltage regulation equipment in new energy distributed power distribution areas，a two-stage voltage regulationcircuit topology based on a DC-link capacitor-free structure was proposed. Based on this topology，a ...

Abstract：The contact electrical contact fault of gas insulated switchgear（GIS）will affect its electricalperformance. A multi-physics coupling model of GIS contact vibration was first established to address the difficultyin diagnosing contact faults. An experimental platform for high-current detection of GIS was buil...
