Pulse with modulation inverter generation using a correction co-efficient and a reference to the ratio to obtain a real duty ratio |
摘要 |
An inverter generation apparatus comprising means to obtain a reference duty ratio of predetermined switch elements of an inverter on-off driven to each of switch timings so as to have a desired waveform of an AC voltage obtained across load connection terminals, means to obtain correction coefficient for the duty ratio relative to a value reflecting a variation in an output voltage of a DC power circuit, means to obtain a real duty ratio by multiplying the reference duty ratio by the correction coefficient whereby the switch elements of the inverter are on-off driven in the real duty ratio so that the desired value of the AC voltage across the load connection terminals.
