Title: Masakazu Muneshima: Innovator in Power Conversion Technology
Introduction
Masakazu Muneshima is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of power conversion technology, holding a total of 7 patents. His innovative work focuses on enhancing the efficiency and functionality of power conversion devices.
Latest Patents
One of his latest patents is a Neutral-point-clamped multilevel power conversion device. This invention provides a power conversion device in which an on-pulse bias voltage and a neutral-point bias voltage do not interfere with each other. The device includes a polarity judgment section that assesses the polarity of a neutral-point bias voltage calculated by a neutral-point potential fluctuation suppression control section. Based on this polarity, the device selects a corresponding polarity for the on-pulse bias voltage, effectively preventing interference between the two bias voltages.
Another notable patent is a method of controlling a power conversion device. This method involves a correction-term adder that compares the maximum value with the absolute value of the minimum value. The adder selects a signal based on which value is larger and produces a triangular-wave-shaped signal synchronized with the correction amount. This innovative approach enhances the control of voltage command values, improving the overall performance of power conversion devices.
