Title: The Innovations of Toshiyuki Tsunoda
Introduction
Toshiyuki Tsunoda is a prominent inventor based in Maebashi, Japan. He has made significant contributions to the field of electrical engineering, particularly in power supply technology. With a total of 8 patents to his name, Tsunoda's work has had a considerable impact on the industry.
Latest Patents
One of Tsunoda's latest patents focuses on a power supply unit that performs high-accuracy overcurrent detection while significantly reducing losses resulting from current detection. The design includes a switch section that outputs the voltage between both terminals of a current detection resistor. This is achieved using an AND signal from a hysteresis comparator and a pre-driver output signal. The voltage is then filtered by an electrostatic capacitor element and a resistor before being inputted to a comparator. The comparator compares the signals at its two input terminals and outputs the result to a digital filter. When an overcurrent begins to flow, the voltage levels at the comparator's input terminals are inverted, prompting the comparator to output an inversion signal to the digital filter. Ultimately, the digital filter generates a detection signal for the overcurrent detection circuit after a predetermined time has elapsed.
Career Highlights
Throughout his career, Tsunoda has worked with notable companies such as Hitachi, Ltd. and Renesas Electronics Corporation. His experience in these organizations has allowed him to refine his skills and contribute to various innovative projects.
