Abstract

The invention discloses a fan system to connect a power supplier electrically, which comprises the following parts: first switch, second switch, coil and driving device, wherein the driving device consists of third switch and fourth switch; the first, second, third and fourth switches and coil form bridged connection.

Description

technical field [0001] The invention relates to a fan system, in particular to a fan system capable of increasing output power and reducing manufacturing cost. Background technique [0002] Due to the continuous increase of the information processing capacity of the current electronic system, the heat generated is also increased accordingly. However, according to the user requirements that most electronic systems emphasize fast, continuous and uninterrupted, the heat dissipation requirements in the electronic system are getting more and more attention. There are more and more heat dissipation products derived from various products, and the most efficient and widely used fan system is currently on the market. [0003] Please refer to FIG. 1, which discloses a fan system 1, which is electrically connected to a power supply 2 to receive power. The fan system 1 is mainly composed of a driving device 10, a sensing component 20, a first A switch S1, a second switch S2, a third sw...
