ALTERNATIVE SOURCE ENERGY CONTROL Russian patent published in 2013 - IPC H02J9/06 

FIELD: electrical engineering.

SUBSTANCE: system includes an energy conversion system containing: a DC to AC energy converter; the first output configured for connection to the electric mains; the first input configured for connection to the electric mains; the second outputs, each of them configured for connection to the corresponding DC load; the line circuit breaker connected to the converter and to the first output; load interrupters connected to the converter, the second outputs and the first input; and a controller connected to the load interrupters and the first output and configured so that to determine whether the electric mains energy satisfies at least one criterion; the controller is additionally configured for control of the line circuit breaker and the load interrupters for the converter connection to the first output and the first input connection to the second outputs if at least one criterion is satisfied or, if otherwise, for control of the line circuit breaker and the load interrupters for the converter disconnection to the first output and the converter connection to at least one of the second outputs.

EFFECT: improving reliability and safety.
