Assignee: nan
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H | IPC H

Claim 1:
2. A light emitting diode (LED) driver, comprising:
an AC input;
an isolation barrier having a primary side and a secondary side;
at least one output to drive one or more LEDs;
primary side circuitry coupled between the AC input and the primary side of the isolation barrier, the primary side circuitry comprising at least one primary side sensing circuit and power factor correction converter that includes a first primary side sensing circuit of the at least one primary side sensing circuit;
secondary side circuitry coupled between the secondary side of the isolation barrier and the at least one output, the secondary side circuitry including at least one secondary side sensing circuit;
a communication interface; and
a processor communicatively coupled to the at least one primary side sensing circuit, the at least one secondary side sensing circuit and the communication interface, and programmed to:
determine whether a power anomaly or fault has occurred based on both first data received from the at least one primary side sensing circuit and second data received from the at least one secondary side sensing circuit; and
transmit a message to an external controller through the communication interface in response to determining that the power anomaly or fault has occurred.
