With a total of 2 patents to his name, Kobayashi's work showcases his innovative approach to solving complex electrical challenges.

Latest Patents

Kobayashi's latest patents include an "X-ray high voltage generator protected against fault by backup system." This invention features a second inverter portion connected in parallel with the first inverter portion, which consists of an inverter circuit and an inverter driving circuit. If an inverter current detector identifies an abnormality in the electric current flowing through the inverter circuits, the system allows the use of the second inverter portion by switching a control mechanism.

Another significant patent is the "High voltage power supply system including inverter controller." This system incorporates a DC-to-DC converter that produces a DC low voltage, along with a DC-to-AC inverter connected to a step-up transformer. This setup generates an AC high voltage by transforming an AC low voltage obtained from the DC low voltage. The inverter controller manages the operation time period of the DC-to-AC inverter, ensuring that a residual charge stored in a capacitor is rapidly discharged, thus preventing unwanted AC high voltage induction.
