Abstract: The present invention saves space by having an image sensor testing system that includes an image capturing module, an image storage module, and a signal processing module that are integrated on a mainboard. The mainboard uses multiple wires to respectively electrically connect to the image capturing module, the image storage module, and the signal processing module, and the image storage module is electrically connected to the image capturing module and the signal processing module. The image capturing module captures an image signal generated by an image sensor, the image storage module stores the image signal, and the signal processing module processes the image signal into a processed image signal and analyzes the processed image signal to obtain an image test value. The image capturing module and the signal processing module both directly access the image storage module, allowing the image test value to be calculated with less processing time.

Abstract: Disclosed is an uninterruptible power supply, including a rectifier for generating a DC voltage; an energy storage unit; an inverter for converting the DC voltage into a three-phase modulating voltage; a filter; a bypass switch circuit for selectively outputting a three-phase AC voltage or the three-phase modulating voltage as a three-phase load voltage; and a control circuit for controlling the operation of the uninterruptible power supply. The control circuit may use a flux compensation block with different operating modes to adjust the three-phase load voltage at the startup phase of a second inductive load and at the stable phase of the second inductive load, thereby compensating or correcting the flux of the second inductive load to prevent the flux distribution of the second inductive load from being saturated.

Abstract: The present invention discloses a flux linkage compensator, which applies to an UPS system and comprises a load transformer flux linkage observer, a compensation voltage command generator, and a flux linkage command generator. The load transformer flux linkage observer generates a load transformer flux linkage signal. The flux linkage command generator generates a flux linkage command signal. The difference between the load transformer flux linkage signal and the flux linkage command signal forms a flux linkage deviation signal. The compensation voltage command generator generates a voltage compensation signal to make the flux linkage deviation signal approach zero. Thereby, the flux linkage compensator can compensate for the flux linkage deviation occurring in starting the UPS system. Thus, the present invention can perform voltage compensation fast and reliably and inhibit the inrush current effectively.
