Power conversion device, control method thereof, rotation sensorless control device, and control method thereof

2:

• The power conversion device according to claim 1, wherein the setting unit includes:
• a random number generating unit that generates a random number;
• and
• a continuation time determining unit that determines the continuation time based on the generated random number.

3:

• The power conversion device according to claim 1,
• wherein the setting unit includes:
• a random number generating unit that generates a random number;
• and
• a transition determining unit that determines whether or not the currently set carrier frequency is caused to transit to a different carrier frequency based on the generated random number and a particular set transition probability value, and
• wherein, in a case where a result of the determination made by the transition determining unit is a transition, the setting unit sets the set carrier frequency to a different carrier frequency and sets one transition probability value among a plurality of mutually-different transition probability values as the set transition probability value.
