Title: Mitsuru Matsukawa: Innovator in Inverter Technology
Introduction
Mitsuru Matsukawa is a notable inventor based in Kyoto, Japan. He has made significant contributions to the field of inverter technology, holding 2 patents that showcase his innovative approach to solving complex electrical engineering problems.
Latest Patents
Matsukawa's latest patents include an "Inverter apparatus comprising switching elements." This invention addresses the challenge of eliminating potential variation during the turn-off time of each Gate Turn-Off (GTO) element. It stabilizes the gate drawing current by ensuring the effective turn-off of the GTO element. The inverter apparatus features a three-phase inverter that includes paired GTO elements, with a control portion designed to prevent simultaneous switching. This function delays the turn-on operation of GTO elements corresponding to phases other than the selected one, thereby enhancing operational stability.
Another significant patent is for a "DC-DC converter and bi-directional DC-DC converter and method of controlling the same." This invention involves a converter circuit with transformers and rectifier circuit portions. It utilizes pairs of switching elements arranged in a full bridge configuration, with series capacitors connected between the converter circuit portions and transformers. The innovative aspect of this design is the shifting of the switching phase of one element relative to another, which optimizes the performance of the converter.
