Latest Patents
One of Higuchi's latest patents is an "AC to DC Converter with Enhanced Buck/Boost Regulation." This innovative power supply design features a closed-loop potential regulated AC-DC system that utilizes a power transformer with dual secondary windings. The compensating transformer is equipped with two compensating windings, which are connected in series with the principal power supply secondary windings. This design allows for effective regulation of output potential by controlling the compensating transformer circuitry, ensuring stability under varying load conditions.
Another significant patent is the "Regulating Electric Power Circuit Arrangement." This invention employs a unique switching circuitry topology that allows transistors to operate in a 1E mode, minimizing noise voltage typically generated in regulating circuits. The design includes a filter inductor that protects the transistors from sudden current changes during overloads, enabling efficient operation. The arrangement also ensures that no current flows in the reverse direction through previously conducting primary circuit diodes, thus eliminating undesirable reverse recovery effects.
