Abstract
Official abstract text for this publication.
Synthesized signal generation circuits are provided to correspond to a U-coil, a V-coil, a W-coil, respectively, and generate synthesized signals by synthesizing a first command signal and a second command signal generated by a command signal generation circuit. CPU output terminals output the synthesized signals. Signal wires are provided with one ends being connected electrically to the CPU output terminals, respectively, and other ends being connected electrically to IC input terminals of a driver IC, respectively. Gate signal generation circuits separate the synthesized signals applied to the IC input terminals to generate first gate signals as gate signals for high-side FETs and second gate signals as gate signals for low-side FETs.
First claim
Opening claim text (preview).
What is claimed is: 1. A rotary electric machine control apparatus for driving a rotary electric machine having a coil set formed of plural coils corresponding to plural phases or terminals of the rotary electric machine, the rotary electric machine control apparatus comprising: a power converter having switching elements forming plural switching element pairs, which correspond to the plural phases or terminals of the rotary electric machine, respectively, each of the switching…
