Modular power converters usable alone in a multiphase power converter
View Patent ↗A power converter module for use alone or with other modules in a multiphase power converter. The power converter module has an enclosure that surrounds internal components to prevent radiation of electromagnetic energy, which internal components also limit conduction of electromagnetic energy. The internal components include an EMI filter, a ripple filter, a power converter, and a control interface that communicates with a control system of a power conversion system. The control interface includes a memory that stores information related to the power converter modules so as to improve interchangability of similar power modules with the multiphase power converter.
1. A power converter module, comprising:
a power converter for converting one of (a) an input into a single phase output and (b) one phase of a multiphase input into an output; and
a control interface connected to said power converter and configured for connection to a control system, wherein said control interface includes nonvolatile memory for storing information regarding the history of operation and other attributes of the power converter module.
2. A power converter module according to claim 1 , wherein said control interface monitors operation of said power converter and shuts it down when predetermined safe operating parameters are not satisfied.
3. A power converter module according to claim 1 , wherein said information regarding the history of operation and other attributes of the power converter module includes at least one of: a counter for operation hours, maintenance history, and identification information.
4. A power converter module according to claim 1 , wherein said control interface provides control information to said control system and said control system uses said control information in controlling the operation of the power converter module.
5. A power converter module according to claim 1 , wherein said control interface controls the operation of the power converter module.
6. A power converter module according to claim 1 , wherein said power converter module includes a DC bus, a switching network and a series impedance network.
7. A power converter module, comprising:
a power converter for converting one of (a) an input into a single phase output and (b) one phase of a multiphase input into an output; and
a control interface connected to said power converter, wherein said control interface includes nonvolatile memory for storing information regarding the history of operation and other attributes of the power converter module.
8. A power converter module according to claim 7 , wherein said control interface monitors operation of said power converter and shuts it down when predetermined safe operating parameters are not satisfied.
9. A power converter module according to claim 7 , wherein said information regarding the history of operation and other attributes of the power converter module includes at least one of: a counter for operation hours, maintenance history, and identification information.
10. A power converter module according to claim 7 , wherein said control interface controls the operation of the power converter module.
11. A power converter module according to claim 7 , wherein said power converter module includes a DC bus, a switching network and a series impedance network.
12. A method of converting power using a power converter module having a power converter and a control interface, the control interface having nonvolatile memory and being connected to the power converter, the method comprising:
converting, by the power converter, one of (a) an input into a single phase output and (b) one phase of a multiphase input into an output; and
storing information regarding the history of operation and other attributes of the power converter module in the nonvolatile memory of the control interface.
13. A method of converting power according to claim 12 , further comprising monitoring, by the control interface, operation of the power converter and shutting it down when predetermined safe operating parameters are not satisfied.
14. A method of converting power according to claim 12 , further comprising storing at least one of a counter for operation hours, maintenance history, and identification information as part of the information regarding the history of operation and other attributes of the power converter module.
15. A method of converting power according to claim 12 , further comprising controlling, by the control interface, the operation of the power converter module.
