摘　　要：根据可再生能源及逆变电源的特点,提出了一种基于太阳能的便携式逆变电源设计方案。通过太阳能光伏板对锂电池进行充电,前级将锂电组12V电压经过推挽式DC-DC高频变压器升压,再通过整流滤波为320V直流电压,后级由全桥式DC-AC电路将320V电压通过SPWM控制逆变为220V、50Hz的标准正弦交流电供用电器使用。该逆变电源可广泛用于长途旅行或野外宿营等小功率设备。Based on renewable energy and the characteristics of inverter,a portable solar-based inverter design.By solar photovoltaic panels charge the lithium battery.The former level after the 12 V DC voltage adopts high-frequency push-pull DC-DC step-up transformer,and then filter through into 320 V.After the class by the full bridge circuit to 320 DC-AC voltage inverter is controlled by SPWM 220 V,50 Hz sine standers for a variety of low-power devices.The inverter has made a effective implementation of overcurrent,overvoltage,undervoltage protection successfully.The inverter is suitable for long distance travel or camping equipment.
