The control circuit includes a cooling fan, a controller, a switch unit, and a control unit. The controller is configured to generate a first pulse width modulation (PWM) signal for controlling the cooling fan to rotate at a first speed and the control unit is configured to generate a second PWM signal for controlling the cooling fan to rotate at a second speed. The switch unit is configured to output the first PWM signal to the cooling fan when the data center is in an active mode and configured to output the second PWM signal to the cooling fan when the data center is in a standby mode."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Control circuit for controlling cooling fan of data center","description":"A control circuit for controlling a cooling fan is defined in a data center.
