Abstract:
A sequential extraction control device for use in a 3-phase DC/AC converter. The 3-phase converter has three single-phase DC/AC converters, each controlled by a respective PWM extractor. Duty factor adjustments are made depending on a current portion of an AC power cycle. A sequential regulator causes the PWM extractors to have non-overlapping duty cycles such that extractions of each of the single-phase DC/AC converters is performed in sequence, rather than concurrently. This improves the efficiency in extracting power from the DC power.

Claim (Index 1):
A sequential energy extraction control device which is configured to control a DC energy extraction sequence and an energy extraction duration time of the three single-phase DC/AC converters which are built in a 3-phase DC/AC converter:\n the first single phase converter in the 3-phase DC/AC converter comprising a first PWM extractor configured to extract first AC power from a DC power source so that the first AC power has a frequency and a first phase that conforms to the power grid convention of the AC power that exists in a first power delivering cable pair of a 3-phase AC power grid; the second single phase converter in the 3-phase DC/AC converter comprising a second PWM extractor configured to extract second AC power from the DC power source so that the second AC power has the same frequency as the first AC power but with a second phase that conforms to the power grid convention of the AC power that exists in a second power delivering cable pair of the 3-phase AC power grid; and the third single-phase converter in the 3-phase DC/AC converter comprising a third PWM extractor configured to extract third AC power from the DC power source so that the third AC power has the same frequency as the first AC power but with a third phase that conforms to the power grid convention of the AC power that exists in a third power delivering cable pair of the 3-phase AC power grid; the sequential energy extraction control device comprising: a sequential regulator configured to cause the first PWM extractor to have a first duty cycle during which the first PWM extractor performs power extraction from the DC power source, causes the second PWM extractor to have a second duty cycle during which the second PWM extractor performs power extraction from the DC power source, and causes the third PWM extractor to have a third duty cycle during which the third PWM extractor performs power extraction from the DC power source; such that the first, second and third duty cycles do not overlap in the time domain, and such that the first, second and third PWM extractors perform extraction sequentially; the sequential regulator further configured to direct duty factor adjustments of the first, the second, and the third duty cycles in accordance with a current time of at least one AC power cycle, to thereby adjust one or more of the first AC power, the second AC power, and the third AC power.
