摘要：介绍了一种修正正弦波输出逆变电源的设计。该设计采用DC/DC和DC/AC两级变换，高频变压器隔离，通过检测直流母线电压来补偿逆变器输出电压有效值。采用修正正弦波，不需要输出滤波电感，提高了电源的功率重量比。实验证明，该方案带载效果良好，成本低廉，性能稳定可靠。

Abstract: A modified sine wave DCAC power inverter was introduced. The power supply consists of two stages which are DC to DC and DC to AC converters. A high frequency transformer was used for isolation. Inverter detects the DC bus level to compensate the AC output voltage. Without the output filter the converter size and weight could be reduced. Experimental results indicate that the design has good load performance, low cost and high reliability.
Key words: inverter; modified sine wave; isolation fault protect
