Abstract
In a method of controlling an inverter for adjusting a periodic inverter output waveform to a desired periodic waveform, an error waveform pattern between an inverter output waveform of the present prescribed period and a desired periodic waveform generated in synchronization with the prescribed period is formed, and the error waveform pattern is added to an inverter driving waveform pattern in the last prescribed period, whereby an inverter driving waveform pattern is updated.
Claims12
A method of controlling an inverter for adjusting a periodic inverter output waveform to a desired periodic waveform, comprising the steps of:
- forming an error waveform pattern between an inverter output waveform of a present prescribed period and a desired periodic waveform generated in synchronization with said prescribed period, and
- adding the error waveform pattern to an inverter driving waveform pattern of a last prescribed period for updating the inverter driving waveform pattern.
A device for controlling an inverter adjusting a periodic inverter output waveform to a desired periodic waveform, comprising:
- memory means for storing an inverter driving waveform pattern of a last prescribed period;
- error waveform pattern generating means for generating an error waveform pattern between an inverter output waveform of a present prescribed period and a desired periodic waveform generated in synchronization with said present prescribed period;
- and
- updating means for adding said error waveform pattern generated by said error waveform pattern generating means to the inverter driving waveform pattern of the last prescribed period stored in said memory means for updating the inverter driving waveform pattern.
