摘要：
An inverter for converting DC power to AC power, an oscillation control circuit for stepwise generating a command value concerning the conversion condition of the inverter, and an operation controller which, when the command value from the oscillation control circuit changes, controls the oscillation control circuit to repetitively generate alternate new and old or present command values before and after change of the command value. Particularly, this invention provides an inverter capable of continuing smooth operation even when the control system has a limited resolution.
