摘要
本文介绍了最新研制的太阳能电池供电的调速冰箱系统。它特别适用于无电的边远地区,为完善我国卫生部门正在实行的计划免疫“冰链”工程起到积极的作用。系统的变频电路采用一种新型的全数字式SPWM方法,可对压缩机进行无级调速,实现电冰箱温度的自动控制和连续运行,具有节能和低噪声的优点。
This paper deals with a recently developed variable frequency refrigerator using solar cells. It is especially used in electricityless regions. A new digital SPWM is adopted in the variable frequency circuit and the speed of the compressor can be changed smoothly. The temperature of the freezer can be controlled automatically and the compressor can be operated continuously. The energy can be saved and the noise of the compressor is reduced.
