【Abstract】 In this paper the inverter techniques for photovoltaic power supply are discussed and it is pointed out that the main factors which affect inverting efficiency are transformer consumption, power electronic switching transistor consumption as well as driving circuit consumption, control circuit consumption at light load operation. On the basis of the discussion, an optimal electric scheme is suggested and its power consumption, harmonic distortion, voltage stability and reliability are analysed.更多还原
