Title: Kousuke Hayakawa and DC/DC Converter Innovation.

Introduction

Kousuke Hayakawa is an inventor associated with Torex Semiconductor Ltd. in Tokyo, Japan. His patent work includes a DC/DC converter designed to regulate power conversion by controlling the operation of switches and monitoring coil current.

Latest Patents

Hayakawa is credited with 1 patent: “DC/DC Converter Having a Coil Connected to a Connection Point Between Two Switches Connected in Series.” The invention describes a converter in which a coil connects to the point between a main switch and a subordinate switch. The switches turn on and off alternately to convert a direct-current input voltage into a predetermined direct-current output voltage.

The converter detects whether the coil current is in continuous or discontinuous current mode while the subordinate switch is on. It then uses the time between the subordinate switch turning off and the connection-point voltage reaching a specified threshold to control the subordinate switch’s on-time in a subsequent cycle.

Career Highlights

Hayakawa’s documented patent contribution focuses on power-conversion circuitry and switch control. The invention’s current-mode detection and timing-based control are intended to support the converter’s operation across different coil-current conditions.

Collaborations

The patent is associated with Torex Semiconductor Ltd., a company working in semiconductor technology. The available information identifies the company connection but does not specify additional collaborators.

Conclusion

Kousuke Hayakawa’s patent describes a DC/DC converter that combines current-mode detection with adaptive subordinate-switch timing, reflecting his contribution to power-conversion innovation.
