METHOD AND APPARATUS FOR INDEPENDENT CONTROL OF MULTIPLE POWER CONVERTER SOURCES |
摘要 |
A method and apparatus for independently controlling multiple power converter sources. In one embodiment, the method comprises determining a ratio of a first set point for biasing a first DC source to a power converter and a second set point for biasing a second DC source to the power converter, wherein the first and the second DC sources are serially-coupled to one another and coupled to an input bridge of the power converter by a filter; and determining, based on the ratio, relative switching times for driving a first diagonal of an input bridge of the power converter and a second diagonal of the input bridge to bias the first DC source proximate the first set point and the second DC source proximate the second set point. |

1. A method for independently controlling multiple power converter sources, comprising:
determining a ratio of a first set point for biasing a first DC source to a power converter and a second set point for biasing a second DC source to the power converter, wherein the first and the second DC sources are serially-coupled to one another and coupled to an input bridge of the power converter by a filter; and determining, based on the ratio, relative switching times for driving a first diagonal of an input bridge of the power converter and a second diagonal of the input bridge to bias the first DC source proximate the first set point and the second DC source proximate the second set point. |
