Title: Hiroki Munechika: Innovator in Inverter Technology
Introduction
Hiroki Munechika is a prominent inventor based in Osaka, Japan. He has made significant contributions to the field of inverter technology, holding a total of 5 patents. His work focuses on improving the efficiency and performance of inverter systems.
Latest Patents
Munechika's latest patents include an inverter apparatus that features a control circuit employing two-phase modulation control. This innovative control circuit reduces switching loss by periodically stopping switching elements. It also minimizes the difference between the time positive switching elements are in the on state and the time negative switching elements are in the on state. The control circuit consists of a command value signal generator that produces command value signals Xu, Xv, and Xw from line voltage command value signals Xuv, Xvw, and Xwu. Additionally, it includes a PWM signal generator that generates PWM signals based on the command value signals Xu, Xv, and Xw. The command value signals Xu, Xv, and Xw are maintained at '0' for a predetermined period and at '2' for another period. This design effectively reduces the difference between the periods for which the PWM signals are low and high.
