His innovative work has led to the creation of a patent that addresses critical issues in switching devices.

Latest Patents

Yoshinaka holds a patent for a "Resonant converter for stabilized operation of switching devices." This invention includes an impedance for short-circuit prevention, which is connected to the secondary winding side of a transformer within a resonant converter. The design comprises a resonant circuit, a D.C. input source, and switching devices. The short-circuit prevention impedance is driven by the current generated in a driving winding, which corresponds to the resonance current at the primary winding side of the transformer. This innovative approach prevents the oscillation from stopping unexpectedly and allows for the oscillation to cease at a timing that avoids generating surge voltage in the switching devices by detecting the current returning to the D.C. input power source. Yoshinaka's patent is a testament to his ingenuity and understanding of complex electrical systems.
