The principle of boundary mode of isolated flyback topology was analyzed, a five-output auxiliary power supply for 3 kW solar power inverter without the optocoupler feedback regulator circuit was presented, with the characteristics of simple structure, low cost, high efficiency and high reliability. The multi-output auxiliary power supply of PV inverter schematic and a high frequency flyback transformer detail design were given. And EMI suppression measures in the solar power inverter auxiliary power supply design was described. This power supply has been already used in an inverter. The experiment results prove that the power supply works well, and its output ripple is small and the transformer works well with no fever phenomenon, and can meet the requirements of solar power inverters.
