Abstract: A step-up conversion module includes a first step-up circuit, a second step-up circuit, a first unidirectional conduction element, and a second unidirectional conduction element. The first step-up circuit includes a first input loop composed of a first inductor and a first switch unit. The second step-up circuit includes a second input loop composed of a second inductor and a second switch unit. The first inductor and the second inductor form a coupling inductor with a common core. The first unidirectional conduction element blocks a first reverse current induced by the coupling inductor to the first input loop. The second unidirectional conduction element blocks a second reverse current induced by the coupling inductor to the second input loop.

Abstract: A smart grid integration system includes an AC grid and at least one power conversion apparatus. The power conversion apparatus includes a control unit and a communication unit. The control unit is coupled to the communication unit and receives a voltage signal corresponding to a voltage of the AC grid. The control unit decomposes the voltage signal into a plurality of frequency components and sets a fundamental component and a plurality of dominant harmonic components as a voltage operation signal. The communication unit receives a current signal corresponding to a current flowing through a circuit node through a current port and generates a current information signal. The communication unit receives the voltage operation signal transmitted from the control unit and calculates power information by multiplying the voltage operation signal and the current information signal.

Abstract: A current detecting apparatus measures an input current or an output current of an electronic apparatus. The current detecting apparatus includes a current detecting module, a direct-current measurement module and a current detecting module. The current detecting module includes a coil configured to electromagnetically couple to a path of an input or a path of an output of the electronic apparatus to obtain a first voltage signal. The direct-current measurement module measures the path of the input or the path of the output to obtain a second voltage signal. The current detecting module converts the first voltage signal into a first current command, and converts the second voltage signal into a second current command. The first current command is an alternating-current component of the input current or the output current. The second current command is a direct-current component of the input current or the output current.

Abstract: An electromagnetic interference shielding configuration of an electronic device includes a housing, a connecting circuit board, at least one EMI filter, and a shielding component. The housing has an accommodating space and a shielding space. A mainboard is disposed in the accommodating space, and a connecting circuit board is disposed in the shielding space and electrically conducted to the mainboard. The at least one EMI filter is disposed on the connecting circuit board and electrically conducted to the mainboard through the connecting circuit board. The shielding component combines with the housing and covers the EMI filter. Thus the EMI filter will not have electromagnetic interferences with external electronic components and provide a stable operation of the electronic device.
