摘要： A totem-pole PFC and a current-sampling unit of the totem-pole PFC are provided. The totem-pole PFC is electrically connected to an AC power source and a DC-to-DC converter, and is electrically connected to a load through the DC-to-DC converter. The current-sampling unit has a first sampling switch and a second sampling switch. The first sampling switch and the second sampling switch are controlled to be turned on and turned off so that a magnetizing current flows through the magnetizing inductor when a magnetizing inductor is magnetized and a demagnetizing current does not flow through the sampling resistor when the magnetizing inductor is demagnetized, thereby increasing the demagnetization efficiency and overcoming superimposed operations to improve current detection and increase conversion efficiency of the power conversion.

摘要： A driving apparatus, a system and a method thereof is provided by the present invention. The driving apparatus has at least an output terminal and includes a driving circuit and a control switch. The control switch is electrically coupled with the driving circuit. The driving circuit receives an input signal and converts the input signal into an analog driving signal. The control switch is controlled by a control signal. When the control switch is turned on, the analog driving signal is able to be sent to the output terminal of the driving apparatus. The control signal further controls the spike current generated as turning on the control switch so as to reduce the spike current. The driving apparatus can be applied to an LCD system, so that the panel and the chips of the LCD system have longer life time, lower electricity consumption and better heat dissipation performance.
