Latest Patents

Itogawa's latest patents include innovative designs such as "Parallel conversion units without an output balancing circuit." This invention features a first capacitor and a second capacitor connected in series through a neutral point on the DC side of an inverter. A first converter receives an input voltage from a power source and outputs a first DC voltage to the first capacitor. Simultaneously, a second converter receives a common input voltage and outputs a second DC voltage to the second capacitor. A control circuit manages the first converter to ensure the first DC voltage aligns with a preset first voltage command value, while the second converter is controlled to match a second voltage command value equivalent to the first.

Another notable patent is the "Grid system and control device of grid system." This invention involves a power conversion device that inputs or outputs power to change a state quantity of a distribution grid connected to a voltage source device. A grid control unit calculates a power command value for the power conversion device, ensuring a drooping characteristic compensates for deviations from a control target. The frequency characteristics of control computation are defined to set control gain values corresponding to different frequency ranges.
