Abstract: An output control method for a controller includes the following steps. At each of detection time points, the controller detects a detection voltage value and a detection current value of a load. In a voltage control mode, the controller generates a setting parameter to control the power amplifier according to part of the detection voltage values. In a current control mode, the controller generates the setting parameter to control the power amplifier according to part of the detection current values. When the controller switches to the voltage control mode or the current control mode, the controller determines a ratio between the detection current value and the detection voltage value at one of the detection time points and the setting parameter is generated according to the ratio. Therefore, the bandwidth is substantially the same no matter if the controller operates in the voltage control mode or the current control mode.

Abstract: A battery simulator for simulating the status of a battery connected to a load component includes a controllable current source, a voltage detector, and a gain controller. The controllable current source supplies an output current to the load component according to a current control signal. The voltage detector measures a detection voltage that is generated in response to the output current flowing through the load component. The gain controller is electrically connected to the controllable current source and the voltage detector and generates the current control signal according to a voltage control signal, a gain control signal and the detection voltage.

Abstract: The present invention relates to an electronic device testing apparatus and a testing method thereof. When the test is completed, a pressing head picks up a tested electronic device from a test socket and places the tested electronic device on an output carrier, the output carrier moves out of a test zone, and an input carrier follows immediately after the output carrier and successively moves into the test zone at the same speed; after the pressing head picks up an electronic device to be tested from the input carrier, the input carrier moves out of the test zone, and the pressing head places the electronic device to be tested in the test socket. Accordingly, in the present invention, the operation of the pressing head is simplified, and the overall test efficiency is improved.

Abstract: A pre-interception device includes an input portion for a fluid to flow in, an output portion for the fluid to flow out, a plurality of diversion flow channels and a plurality of interception portions. Each diversion flow channel is in communication with the output portion and the input portion, is configured to provide turning guidance for flow of the fluid, and has a fluid lift section. The interception portions are configured to form a turbulent flow field in the fluid. The turbulent flow field can have foreign objects flowing through the diversion flow channel be captured. Accordingly, a filtering effect is achieved based on physical properties of the foreign objects. When the pre-interception device is additionally combined with a filter net to form a filtering system, the burden on the filter net is further alleviated, hence extending a service life of the filter net and reducing costs.
