Title: Kota Hamanaka: Innovator in Power Conversion Technology
Introduction
Kota Hamanaka is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of power conversion technology, holding a total of 3 patents. His innovative work focuses on control devices that enhance the efficiency and reliability of power converters.
Latest Patents
Hamanaka's latest patents include a control device and a power conversion device. The control device features a generator simulating unit that generates a phase of output voltage for a power converter by simulating the characteristics of a synchronous generator. It also includes a first voltage command generating unit that produces a first voltage command value to ensure that the AC voltage of a power grid reaches a target voltage. Additionally, a setting unit is incorporated to establish an overcurrent level, while a second command generating unit generates a second voltage command value by limiting the first voltage command based on the overcurrent level. Furthermore, the control device comprises a signal generating unit that creates a control signal for the power converter based on the phase generated by the generator simulating unit and the second voltage command value.
The power conversion device, on the other hand, includes a current suppression control unit that calculates a correction amount for a reference voltage command value to operate a power converter as a voltage source. This unit sets an amplitude value of a voltage command by reflecting the correction amount in the amplitude of the reference voltage command. The correction amount is designed to reduce the amplitude value of the voltage command in response to a decrease in AC voltage at an interconnection point.
