Power converting apparatus, control device, and method for controlling power converting apparatus

A control device for controlling a power converter, comprising:

• a command generator configured to generate a voltage command;
• and
• a signal generator configured to generate a PWM signal such that a first period during which a zero voltage is outputted and a second period during which a non-zero voltage is outputted are adjusted according to the voltage command, and output the PWM signal to the power converter,
• wherein the signal generator is allowed to output the PWM signal which is set such that one first period and one or more second periods exist within an updating cycle of the voltage command, to the power converter.

A method for controlling a power converting apparatus, comprising:

• a command generating process for generating a voltage command;
• and
• a signal generating process for generating a PWM signal such that a first period during which a zero voltage is outputted and a second period during which a non-zero voltage is outputted are adjusted according to the voltage command, and outputting the PWM signal to a power converter,
• wherein the signal generating process includes outputting the PWM signal which is set such that one first period and one or more second periods exist within an updating cycle of the voltage command.
