Abstract: A manufacturing method of a magnetic element includes the following steps: forming a block including a central post and at least one lateral post with magneto-conductive materials; cutting the block along a first plane passing through the central and lateral posts to form a first half body and a second half body; combining the first half body with the second half body to form a first air gap between the central post of the first half body and the central post of the second half body and a second air gap between the lateral post of the first half body and the lateral post of the second half body; and cutting or grinding the combined first half body and second half body along a second plane passing through the central post and the lateral post to form a third half body including the first and second air gaps.

Abstract: A power detection and transmission circuit is provided. The power detection and transmission circuit includes a first conversion circuit, a second conversion circuit and a signal coupling circuit. The first conversion circuit is electrically connected to a power supply module to receive an analog input signal, and is arranged for converting the analog input signal to a first pulse width modulation (PWM) signal. The second conversion circuit is arranged for converting a second PWM signal to an analog regenerated signal, and transmitting the analog regenerated signal to a microcontroller, wherein the microcontroller calculates power information of the power supply module according to the analog regenerated signal. The signal coupling circuit is coupled between the first conversion circuit and the second conversion circuit, and is arranged for coupling the first PWM signal to the second conversion circuit and accordingly generating the second PWM signal.
