Title: **Masaki Tagome: Innovator in Power Conversion Technologies**
Introduction
Masaki Tagome, an esteemed inventor based in Osaka, Japan, has made significant contributions to the field of electrical engineering. With an impressive portfolio of 27 patents, he has pioneered various technologies aimed at enhancing the efficiency and performance of power conversion systems.
Latest Patents
Among his latest innovations are an electric power converting apparatus and an induction heating apparatus. These inventions focus on reducing ripple current in power converters, which include a converter, capacitor, and inverter. Specifically, a current sensor is integrated between the capacitor and the inverter circuit to detect the current flow. A frequency detecting subunit conducts a fast Fourier transform on the waveform detected to identify the frequency component with the largest amplitude. Furthermore, this subunit determines the zero-cross point of that component. A carrier signal control subunit then regulates the PWM carrier signal for driving the converter, ensuring that both the frequency and rise time align with the detected values.
Additionally, Tagome has developed a power converter that effectively minimizes switching noise, which can adversely affect performance. This device consists of a capacitor, switching devices connected in parallel, and a controller that manages individual switching operations. The innovative design allows for at least two closed circuits to mutually cancel out ringing voltages resulting from switching operations, enhancing the overall stability of the system.
