| Abstract: | In order to design an auxiliary switching power supply for photovoltaic inverters,The isolated single-end anti-flyback current-control mode is adopted in the circuit structure.The conclusion that the designed circuit is suitable for PV inverters is obtained by experiment.This experiment involves the switching power supply′s some basic design specifications,the transformer core and winding design,feedback and voltage-stabilizing circuit.The auxiliary switching power supply has been already used in an inverter,which is working well,and whose output ripple is small and transformer has not occured any fever phenomenon.It meets the design requirements. |
