摘要
本文主要讨论了太阳能逆变器技术要求,指出影响逆变器效率的主要因素是变压器及功率开关管的损耗,驱动电路与控制电路的功耗是影响逆变器低负荷运行效率的重要原因。在此基础上提出逆变器最佳电路结构,并对其功率损耗,谐波失真,调宽稳压和可靠性进行了分析。
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.
