METHOD FOR CONTROLLING TEMPERATURE OF INVERTER SYSTEM BY CONTOLLING A FAN

摘要

The present invention relates to a method for controlling the temperature of an inverter system having an inverter and a cooling fan. The method includes a step of obtaining the internal temperature of an inverter and the DC-link voltage of the inverter; and a step of outputting a fan driving control signal for maintaining an driving state or driving the fan when the internal temperature of the inverter is higher than a predetermined fan setting temperature and the DC-link voltage is higher than a predetermined fan driving setting voltage, to the fan.
