Latest Patents

One of Matsumura's latest patents is a control apparatus for a D.C. power transmission system. This invention relates to an apparatus that controls a D.C. power transmission system featuring a line-commutated converter connected between a first A.C. system and D.C. power transmission lines. It performs power conversion between A.C. and D.C. power. The control apparatus includes a voltage detector that monitors the D.C. voltage of the transmission lines and a first control circuit that manages the ignition of the self-excited converter based on the voltage comparison. Additionally, it features a current detector that measures the conversion power of the line-commutated converter, along with a second control circuit for managing its ignition.

Another significant patent is the thyristor apparatus employing light-triggered thyristors. This apparatus includes forward voltage detecting circuits that monitor the voltages applied to light-triggered thyristors. The thyristor number detecting circuit ensures that the thyristors are activated simultaneously when a specific number of them receive forward voltages. This design prevents damage to overvoltage suppressing elements in the event of partial commutation failure.
