Embodiment 1

[0070] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Figure 1 to Figure 11 Example 1 of the present invention is shown. Such as figure 1 As shown, the compressed air manufacturing device 1 includes: a solar cell 2, which converts sunlight into electrical energy; a maximum output point tracking device 3 (MPPT: Maximum Power Point Tracker, maximum power point tracking device), which makes the output of the solar cell 2 The electric power [voltage×current] is always at the maximum state; the input voltage is fixed to the control mechanism 4; the DC motor 5 is the drive motor; and the air compressor 6 is driven by the DC motor 5. When the output power of the solar cell 2 exceeds the rated output of the DC motor 5 of the air compressor 6, the input voltage constant control means 4 controls to maintain the DC voltage to the DC motor 5 at a constant voltage corresponding to the rated output.

Abstract

Provided a compressed air producing device less affected by weather fluctuation and capable of efficiently producing compressed air. This compressed air producing device is provided with an air compressor 6 producing compressed air by compressed air producing parts having cylinders and pistons; a DC motor 5 of the air compressor 6; a solar battery 2 converting a sunbeam to electric energy; and a control means for performing drive control of the air compressor 6 by output of the solar battery 2. The air compressor 6 is a multi-cylinder type having the plurality of compressed air producing parts. When the output of the solar battery 2 becomes below a predetermined value due to change in illumination of the sunbeam, the control means performs control to change the number of the compressed air manufacturing parts producing compressed air. Therefore, load of the DC motor 5 is reduced and stable drive can be continued.

Description

technical field [0001] The present invention relates to a compressed air manufacturing device using solar cells. Background technique [0002] Since solar cells have the characteristic that the generated power fluctuates violently due to changes in the altitude of the sun and weather, it is not suitable as a power source for AC drive motors (induction motors) that require stable power supply. As a solution to this, generally, there is a method of temporarily charging the electric power generated by the solar cell in the storage battery to stabilize the electric power, and supplying the electric power to the AC motor. However, since this method requires a large-capacity storage battery, it becomes expensive, and requires enormous labor and expense for maintenance such as replacement due to life. [0003] Therefore, there has been proposed a rotation control device (for example, Patent Document 1). This rotation control device is a control device that uses a solar battery as ...
