Latest Patents

Kanao holds a patent for a distributed power supply system. This system is designed to prevent simultaneous disconnection from the grid when there is an instantaneous drop in grid voltage. The technology involves controlling an inverter circuit based on a control signal derived from comparing a predetermined carrier signal with voltage command signals of three phases. This system effectively converts DC power to AC power, supplying it to a three-phase AC power grid. The invention generates fundamental wave signals from the grid voltage and creates a reference cosine wave signal, which is then used to produce a third harmonic signal. The combination of these signals results in voltage command signals for the three phases.
