**Title: Exploring the Innovations of Inventor Hideki Yoshida**
Introduction
Hideki Yoshida, an accomplished inventor based in Tochigi-ken, Japan, has made significant contributions to the refrigeration technology sector. With a total of two patents to his name, Yoshida has developed innovative solutions that enhance the efficiency and functionality of refrigerators.
Latest Patents
Yoshida's latest patents focus on advanced refrigeration systems. The first patent describes a sophisticated refrigerator design that incorporates a motor-driven compressor, an inverter for motor control, and a converter responsive to AC signals. This combination allows for the output of multiple variable DC voltages, which are controlled through a converter control mechanism. Notably, the design ensures that the lowest voltage can disable the boosting function of the converter, enhancing efficiency.
The second patent further innovates on inverter control within refrigerators. It addresses the common issue faced at the preset minimum rotating speed of the compressor motor, where efficiency typically drops due to switching loss in the power element. Yoshida's invention optimizes the control of the converter circuit by turning it off when certain conditions are met, improving the overall efficiency of the compressor motor when the internal temperature approaches the preset level.
