ALEXANDRIA, Va., Feb. 17 -- United States Patent no. 12,556,122, issued on Feb. 17, was assigned to NIDEC Corp. (Kyoto, Japan).
"Inverter circuit and motor module" was invented by Kotaro Kataoka (Kyoto, Japan).
According to the abstract* released by the U.S. Patent & Trademark Office: "An inverter circuit includes at least three output terminals, a first input terminal, a second input terminal, and at least three series bodies. A total switching duration and a one-phase fixed duration are present within a single cycle of AC output. The waveform of each phase of an output voltage is such that a shared offset wave is deducted from a sinusoidal waveform. The waveform of the offset wave matches one phase of the sinusoidal waveform, or matches...
