Latest Patents

Kiyoshi Nakata holds a patent for a Power Conversion System. The abstract of this disclosure describes a system that extracts direct current from an AC power supply of variable frequency and voltage through a PWM converter. In low source voltage regions, the converter input current is limited to maximize DC power while considering the voltage drop of the power supply. The system ensures a power factor of "1" and limits the current to an allowable maximum. In high source voltage regions, the quadrature component of the input voltage is controlled to maintain the converter input voltage below a predetermined value, securing maximum power across the entire operational range. Additionally, the system allows for cooperative operation with a battery connected to the DC side, ensuring proper charging.
