Latest Patents

Among his most notable innovations are two recent patents that showcase his ingenuity. The first, titled *Control Device for Power Converter*, introduces a technology that enables a power converter to convert a DC voltage, which includes a pulsation component, into an AC voltage. This AC voltage is then supplied to a synchronous electrical motor. This device features a pulsation component detection unit that identifies the pulsation component and a control circuit that adjusts the load angle of the motor according to the instantaneous value of the pulsation.

The second patent, *Inverter with Reduced Output Ripple*, focuses on a specialized inverter device. This invention consists of a converter section, inverter section, and a control device. The converter section efficiently full-wave rectifies a three-phase AC voltage, generating a DC voltage that includes a ripple component. The inverter section then transforms this DC voltage into a usable AC voltage for motor applications. The control device is particularly innovative, managing the inverter to ensure that the phase of the d-axis voltage leads that of the q-axis voltage, thus minimizing ripple effects.
