Design of auxiliary power supply for the solar PV inverter

Abstract

In order to design PV inverter auxiliary power supply, circuit with isolated single-ended anti-flyback current-control mode,is obtained by experimental design of the circuit for the conclusions of PV Inverter. This experiment involves some of the basic switching power supply design specifications,the transformer core and winding design,feedback and regulation circuit.The auxiliary switching power supply is already used in the inverter,which is high stability,output ripple is small and the phenomenon of transformer no fever,meets the design objectives. © 2011 Springer-Verlag.
