置。 ９Converts the output of solar cells to alternating current for fans, pumps, etc.2
In an inverter control device that detects the output voltage of a solar cell and is equipped with a frequency setting circuit that controls the output frequency of an inverter that operates a load with multiplication reduction torque characteristics at a predetermined frequency based on a frequency command signal. The above-mentioned comparator has a built-in DC/DC converter that converts it into a correction signal level, and a plurality of output patterns to output the optimum correction signal according to the torque frequency characteristics of the load.
- If the output of the solar cell decreases when the output of the solar cell is compared with an amplifier that amplifies and converts the evening output to an output level according to the characteristics of the load and the above frequency command signal is used as the first frequency command signal. - A small priority circuit that outputs a second frequency command signal according to the output voltage to lower the upper limit output frequency of the inverter, and adjusts the frequency and voltage of the inverter based on the second frequency command signal. An inverter control device characterized by having a configuration for controlling an inverter. 9
