Embodiment Construction

[0053] Hereinafter, various embodiments of the present invention will be disclosed with the accompanying drawings. For the sake of clarity, many practical details will be described together in the following description. It should be understood, however, that these practical details should not be used to limit the invention. That is, in some embodiments of the invention, these practical details are unnecessary. In addition, for the purpose of simplifying the drawings, some well-known and conventional structures and elements are shown in a simplified and schematic manner in the drawings.

[0054]Herein, when an element is referred to as being "connected" or "coupled", it may be referred to as "electrically connected" or "electrically coupled". "Connected" or "coupled" may also be used to indicate the cooperative operation or interaction between two or more elements. In addition, although terms such as "first", "second", . . . are used herein to describe different elements, the...

Abstract

The invention relates to a fan system and a fan driving method. The fan system comprises a first fan and a second fan which are respectively used for operating according to a first driving signal and a second driving signal and generating a first rotating speed signal and a second rotating speed signal. The first rotational speed signal has a first phase and the second rotational speed signal has a second phase. The second fan is electrically connected to the first fan to receive the first rotating speed signal and obtain a detected phase difference between the first phase and the second phase. The second fan is further used for selectively increasing or reducing the duty ratio of the second driving signal according to the detected phase difference, so that the second phase is adjusted to maintain a preset phase difference with the first phase, and unstable power supply caused by phase overlapping is avoided.

Description

technical field [0001] The present disclosure relates to a fan system and a fan driving method, especially for controlling a plurality of fans to maintain the same rotational speed. Background technique [0002] With the advancement of science and technology, the operating frequency of various electronic devices has increased, but the increase in operating frequency has caused the internal temperature of the electronic device to increase relatively during operation. In order to prevent the high temperature from affecting the operation of the electronic device, Even if the electronic device is damaged, the presence of the fan is indispensable for maintaining the operation of the electronic device. [0003] A fan system often includes multiple fans, which are controlled at the same speed. However, when the fan is actually running, its rotational speed often fluctuates due to various variables or different operating requirements, and may also need to be adjusted for power supp...
