摘要： In a light power generation system, a control device, a control method, and a program, efficient power can be supplied. The maximum power detection unit operates a MOSFET in a power converter circuit and open-circuits both ends of a solar cell panel in the maximum power detection mode. After that, the maximum power detection unit short-circuits both ends of the solar cell panel, detects a maximum power by monitoring the output power of the solar cell panel during a period from the open state to the short-circuited state, and defines the voltage of the solar cell panel as an optimal voltage when detecting the maximum power. In a tracking operation mode, the control unit performs PWM control with respect to the MOSFET by defining the optimal voltage to be a reference signal. Operations are repeated between the maximum power detection mode and the tracking operation mode.

摘要翻译： 在光发电系统中，可以提供控制装置，控制方法和程序，能够提供有效的功率。 最大功率检测单元在功率转换器电路中操作MOSFET，并以最大功率检测模式对太阳能电池板的两端进行开路。 之后，最大功率检测单元短路太阳能电池面板的两端，通过在从断开状态到短路状态的期间监视太阳能电池面板的输出功率来检测最大功率， 当检测到最大功率时，太阳能电池板的电压为最佳电压。 在跟踪操作模式中，控制单元通过将最佳电压定义为参考信号来执行关于MOSFET的PWM控制。 在最大功率检测模式和跟踪操作模式之间重复操作。
