    • A full-bridge circuit for a heat dissipation system. The heat dissipation system further includes a fan and a control circuit. The control circuit outputs a first control signal and a second control signal. The full-bridge circuit includes a first control line having a first switch and a third switch serially coupled, a second control line includes a second switch and a fourth switch serially coupled, and a induction coil having one terminal coupled between the first and third switches and the other terminal coupled between the second and fourth switches. The ON/OFF states of the first and second switches are controlled by the first and second control signals respectively. The ON/OFF states of the third and fourth switches are controlled by two driving voltage sources respectively.

    • A driving circuit for switches of direct current fan motor is disclosed. The driving circuit includes a plurality of switches, a first control circuit, and a second circuit. The switches are driven by a first pulse width modulation signal and a second pulse width modulation signal, and they are electrically connected with the direct current fan motor in a bridge manner. A third pulse width modulation signal is used to drive the first control circuit connected to at least one of the switches driven by the first pulse width modulation signal. A fourth pulse width modulation signal is used to drive the second control circuit connected to at least one of the switches driven by the second pulse width modulation signal. Especially, either the first pulse width modulation signal or the second pulse width modulation signal is selected as the third pulse width modulation signal or the fourth pulse width modulation signal.
