Patent JP-2012055112-A (JP)
Title: Power conversion apparatus, and electric power steering device using the same
Inventor: SUZUKI TAKASHI
IPC: H02P27/06
Filed: 2010-09-02
Abstract: PROBLEM TO BE SOLVED: To reduce switching loss by decreasing switching frequency of a switching element in a power conversion apparatus equipped with an inverter part and a step-up circuit part.SOLUTION: An inverter control part of a power conversion apparatus of a three-phase rotary electric machine subjects a duty command signal DL related to a voltage applied to a winding pair to a low solid two-phase modulation process so as to agree with a minimum value Rmin in a duty range capable of outputting a minimum value. Since a switching element of one phase among three phases does not perform switching at a valley point OL of a PWM reference signal P during PWM one cycle, switching frequency decreases to 2/3. A step-up circuit control part causes the frequency of a step-up PWM reference signal DB to be identical with the frequency of the PWM reference signal P of an inverter part. Consequently the switching frequency of the switching element at a step-up circuit part becomes a half when compared with a conventional technology. Thus, a switching loss is reduced.
