摘要： A system is used to measure a fan rotational speed. The system includes a main controller, a first socket coupled to the linear fan, a second socket connected to the main controller, and an optical fiber amplifier connected to the main controller. A PWM (pulse width module) fan is coupled to the second socket, the PWM fan sends a first rotational speed signal, which represent a rotation speed of the PWM fan, to the main controller via the second socket. The optical fiber amplifier is capable of radiating light on fan blades of the linear fan, and sensing light reflected by the fan blades to count a rotational speed of the linear fan, and generating a second rotational speed signal which represents a rotational speed of the linear fan. The optical fiber amplifier sends the second rotational speed signal to the main controller.

摘要： A pulse modulation method for adjusting pulse signals according to a working voltage of a load, the method includes the following steps. The working voltage of the load is detected by a feedback terminal of a PWM controller. Whether the load is a light load or a heavy load is determined, if the load is a light load, a pulse skipping mode is entered; the voltage output to the load is detected by the feedback terminal. Whether the voltage output to the load is normal is determined, if the voltage output to the load is low, the pulse skipping mode is stayed for a number of clock cycles; the voltage output to the load is detected to determine whether the voltage is normal. If the voltage output to the load is still low, the pulse skipping mode is jumped out and a normal working mode is entered.
