数字控制400VA纯正弦波逆变器系统设计
Design of 400VA Pure Sine Inverter System with Digital Control
Demands for sine inverters increase significantly with development of photovoltaic generate electricity.Traditional inverters exhibit various disadvantages,e.g.a bulk volume,low efficiency,complexity of design,and poor reliability.A 400VA sine inverter with a high-frequency link has been designed to overcome those shortcomings and there are system design,software design and supervisory circuits for over-current,over and under voltage protection and so on.Experimental results show that the inverter has a stable output voltage with high reliability,litter volume,high reliability and small THD.It is very suitable for high quality output voltage occasions.
