20140192567 | METHODS FOR CONTROLLING ELECTRICAL INVERTERS AND ELECTRICAL INVERTERS AND SYSTEMS USING THE SAME - A system for generating a duty cycle control signal for controlling an inverter power train providing an output current waveform to a grid operating with a grid voltage waveform compares a reference current waveform shaped to the grid voltage waveform with the output current waveform to generate an error signal. The error signal is used to generate a corrective control action signal, which is combined with a feed-forward signal representing a nominal duty cycle generated with a feed-forward function. The combination of the feed-forward signal and the corrective control action signal provide the duty cycle control signal. | 07-10-2014 |
