Regulation of powertrain converter circuit

摘要

Regulation of powertrain converter circuits is provided. The power conversion may include converting between direct current and alternating current and the regulation may include reduction of distortion on switching start up and zero-crossings. Solid-state implementations, code implementations, and mixed implementations are provided.

1. A powertrain controller system configured to regulate a powertrain converter circuit using a process comprising:
determining that a powertrain converter circuit is within a start-up period or determining that output current from the powertrain converter circuit is approaching a reference indicating a reversal in polarity of the output current from the powertrain converter circuit, or both; after determining, and when a determination is made that the powertrain converter circuit is within a start-up period, triggering a correction signal that serves to reduce output current distortion during the start-up period; after determining, and when a determination is made that the output current from the powertrain converter circuit is approaching a reference indicating a reversal in polarity, triggering a correction signal that serves to reduce output current distortion at least before, during or after reversal of polarity of the output current, wherein the powertrain converter circuit comprises switches configured to receive switching signals that serve to operate the switches to convert current from an energy supply at least between direct current and alternating current.
