Latest Patents

One of his latest patents is an "Apparatus for automatically measuring a relatively wide range of leakage currents." This invention provides a leakage current measurement apparatus that automatically selects from non-inductive shunt resistors of 10Ω, 100Ω, and 1000Ω. It is designed to measure leakage currents of outdoor isolation materials for ultra-high voltage applications. The apparatus can measure a wide range of leakage currents with high precision, even from remote locations, as it adjusts the measurement range automatically based on user presets. Additionally, it is protected against surges that may occur due to ultra-high voltage.

Another significant patent is the "Multi-pulse HVDC system using auxiliary circuit." This invention minimizes the number of thyristors required by incorporating a thyristor auxiliary circuit in a conventional 12-pulse thyristor HVDC system. It allows for the implementation of multi-pulse configurations, such as 24-pulse, 36-pulse, and 48-pulse converters, without the need for additional thyristor stacks. The system features an upper and lower thyristor converter installed in a Δ-Δ-Y transformer, along with current smoothing reactors and a direct voltage dividing condenser.
