Pre-magnetizing a transformer connected to a modular multilevel power converter
The present invention is concerned with pre-magnetizing a Modular Multilevel power Converters connected transformer in order to moderate inrush currents upon connecting the transformer to an electric grid. The invention takes advantage of the high amount of stored energy in MMC converters as compared to other converter types. This stored energy is used to pre-magnetize the converter-connected transformer, therefore no additional or dedicated pre-magnetizing hardware is required in addition to the charging hardware provided to charge the converter capacitors. As the transformer pre-magnetizing takes place subsequent to the converter charging, the converter charging circuit is not used to, and therefore does not need to be designed to, directly magnetize the transformer.
Multi-pack and component connectivity detection
Techniques for enabling multi-pack and component connectivity detection are provided. In some configurations, individual PCMs can test the connectivity between components of a device without the need to operate the components. For example, PCMs configured in accordance with the present disclosure can test the connectivity between a motherboard, a display circuit, a camera, and a number of battery packs without the need to operate the motherboard, display circuit, camera, etc. In some configurations, conductors that are part of cables and connectors used to connect the components can be used to determine the state of one or more connections. When a signal that runs through the conductors meets one or more criteria, the PCMs of a device cause a predetermined delay prior to enabling one or more components. By testing the connectivity between components before each component transitions to an operational state, other problems caused by faulty connections can be mitigated.
