CONTROL OF LEAKAGE CURRENTS IN SYSTEMS WITH A PLURALITY OF PARALLEL INVERTERS |
摘要 |
There is described an electrical energy conversion system comprising: at least a first inverter (1) and at least a second inverter (2), whose outputs are connected in parallel; at least a first DC voltage source (PV1) connected to the input of the first inverter (1) and a second DC voltage source (PV2) connected to the input of the second inverter (2); a ground connection of the first inverter (1) and a ground connection of the second inverter (2). The ground connection of said inverters comprises a ground connection branch (1G; 2G) with a current sensor (5/1; 5/2) which supplies a signal proportional to a leakage grounding current (Ileak) measured in said ground connection branch (1G; 2G). Through the signal proportional to the leakage current measured a feedback signal is generated to control the leakage current (Ileak). |
