Latest Patents

One of Cheng-Chieh Liu's latest patents is a method of starting a fan using an open loop starting stage with a decreasing drive signal value. This method involves controlling a fan during its start-up stage through two distinct time periods. During the first time period, a first driving signal is continuously provided to drive the fan, while in the second time period, a second driving signal is used. The first driving signal's value gradually decreases until it matches the value of the second driving signal. Notably, the first signal decreases non-linearly, while the second signal remains constant. This innovative approach allows for adjustments in the time periods for different fans, ensuring optimal performance.
