Abstract
An inverter system includes a level skip prevention control section. The level skip prevention control section is configured to: in response to an upward shift of an output voltage level of a first one of phases, set a counter for inhibiting upward shifting of the output voltage level of the first phase during a predetermined duration, and set a counter for inhibiting downward shifting of an output voltage level of a second one of the phases other than the first phase during a predetermined duration; and in response to a downward shift of the output voltage level of the first phase, set a counter for inhibiting downward shifting of the output voltage level of the first phase during a predetermined duration, and set a counter for inhibiting upward shifting of the output voltage level of the second phase during a predetermined duration.
