Latest Patents

One of Kunii's latest patents involves a sophisticated DC-DC converter. This innovative device achieves a high level of signal superimposition in an AC manner onto the output of an insulator, such as a photocoupler. The design of this converter has very few limitations regarding constant design, phase correction, starting characteristics, and short-circuit protection. The secondary-side control circuit detects the output voltage and feeds back a control signal to a drive control circuit on the primary side via a photocoupler. This configuration ensures that the primary side of the DC-DC converter is insulated from the secondary side. Additionally, the output signal of an auxiliary power-supply circuit is superimposed in an AC manner onto the control signal through a coupling capacitor. The drive control circuit stabilizes the output voltage of the secondary-side circuit based on the control signal.

Another significant patent focuses on a power supply that converts a first direct-current voltage into a second direct-current voltage. This power supply includes a reference voltage generating circuit, a control circuit for managing the output voltage according to the reference voltage, and a short-circuit detecting circuit. The latter performs an output short-circuit protection operation by detecting short circuiting and decreasing the reference voltage to lower the output voltage.
