Abstract
An apparatus configured for use with a microinverter of an energy management system is provided. For example, apparatus can comprise a cascaded current transformer configuration comprising a first current transformer having a first primary winding configured to couple to a secondary winding of a power transformer of the microinverter and having a first secondary winding coupled to a second primary winding of a second current transformer having a second secondary winding coupled to a measurement device configured to measure a current of the microinverter.
Claims12
An apparatus configured for use with a microinverter of an energy management system, comprising:
- a cascaded current transformer configuration comprising a first current transformer having a first primary winding configured to couple to a secondary winding of a power transformer of the microinverter and having a first secondary winding coupled to a second primary winding of a second current transformer having a second secondary winding coupled to a measurement device configured to measure a current of the microinverter.
An energy management system, comprising:
- a DC power source connected to a power converter to convert DC power from the DC power source to grid-compliant AC power that is coupled to an AC bus;
- and
- a cascaded current transformer configuration comprising a first current transformer having a first primary winding configured to couple to a secondary winding of a power transformer of the power converter and having a first secondary winding coupled to a second primary winding of a second current transformer having a second secondary winding coupled to a measurement device configured to measure a current of the power converter.
