Latest Patents

One of his latest patents is an uninterruptible power supply that includes a rectifier for generating a DC voltage, an energy storage unit, and an inverter for converting the DC voltage into a three-phase modulating voltage. This invention also features a filter, a bypass switch circuit for selectively outputting a three-phase AC voltage or the three-phase modulating voltage, and a control circuit that manages the operation of the uninterruptible power supply. The control circuit utilizes a flux compensation block with various operating modes to adjust the three-phase load voltage during the startup phase and stable phase of a second inductive load. This innovation aims to prevent the flux distribution of the second inductive load from becoming saturated.

Another significant patent is a flux linkage compensator for uninterruptible power supply systems. This invention 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, while the flux linkage command generator produces a flux linkage command signal. The difference between these signals forms a flux linkage deviation signal, which the compensation voltage command generator uses to generate a voltage compensation signal. This allows the flux linkage compensator to effectively compensate for any flux linkage deviation that occurs during the startup of the UPS system.
