摘要： The present disclosure discloses a converter system, which at least includes the first and second back-to-back converters. The first back-to-back converter includes a first rectifier module and a first inverter module. The first rectifier module is used to convert a first AC voltage to a first DC voltage. The first inverter module is used to convert the first DC voltage to a second AC voltage. The second back-to-back converter includes a second rectifier module and a second inverter module. The second rectifier module is used to convert the first AC voltage to a second DC voltage. The second inverter module is used to convert the second DC voltage to the second AC voltage. The converter system can suppress the circular current through the synchronous operation of the first and second rectifiers or the synchronous operation of the first and second inverters.

摘要： A starter of the grid-connected inverter and a control method thereof are disclosed. The starter comprises a controller, and a first switch and a first resistor connected in parallel. The controller includes an input end, and first and second output ends. The input end inspects the DC voltage signal from the inverter. When the DC voltage exceeds a predetermined voltage threshold, the first output end sends a first control signal to turn on the first switch, and the second output end sends a second control signal to make the grid-connected inverter enter into a chopping mode. There is a delay period between the send time of the first control signal and that of the second control signal.

摘要： A control method for a first synchronous rectifier and a second synchronous rectifier in a switching power converter is presented. The switching power converter includes a transformer, and a first switching device and a second switching device connected in series and in parallel with an input voltage source. The first synchronous rectifier is connected with a low end of a secondary winding of the transformer. The second synchronous rectifier is connected with a high end of the secondary winding of said transformer. The first switching device is connected with a high end of the input voltage source, and the second switching device is connected with a low end of the input voltage source. The control includes the steps of driving the first switching device to an on state and the second switching device to an off state; and driving the second synchronous rectifier to an off state after the second switching device has been driven to an on state, such that a power is delivered from the primary winding to the secondary winding.
