Latest Patents

Tsuchihashi holds a patent for a "Three-phase inverter apparatus and control method thereof." This invention includes an inverter main circuit in three phases, which utilizes a plurality of semiconductor switching devices to convert a DC voltage into three-phase AC voltages. These voltages are supplied to a pulsating load. The apparatus features a current detector that detects first and second output currents from the inverter main circuit, as well as a voltage detector that measures first to third output voltages. A control circuit generates a command compensation value by dividing a current RSM obtained from the output currents by an average value of the current RSM. This value is then used to create compensated control commands for each switching device based on the output voltages.
