变频电源设计

Design of Inverter Power Supply

为了设计一个可以产生频率在20Hz^100Hz范围可调、输出电压为36V的单相正弦波变频交流电源。采用32位的单片机为主控制器,系统由控制模块、主电路模块、辅助电源模块、驱动模块和检测模块组成。通过实物测试,系统测试结果表明设计的单相正弦波变频电源,输出频率在要求范围内可调,电压调整率和负载调整率均符合设计要求,输出电压波形无明显失真,设计电源可以作为高校学生实验,电子电路设计产品的测试电源。

In order to design a frequency can be generated in the range of 20Hz-100Hz adjustable, the output voltage of 36V single phase sine wave inverter AC. The system consists of control module, main circuit module, auxiliary power module, drive module and detection module. The system test results show that the single-phase sine wave frequency conversion power supply design, the output frequency is adjustable in the required range, voltage regulation and load regulation are in line with the design requirements, the output voltage waveform without obvious loss of it, design of power supply can be used as the experiment of college students, to test the power electronic circuit product design.
