Abstract
An electronic device for detecting a load type is described. The electronic device includes zero-cross circuitry configured to detect a line voltage zero cross and includes switching circuitry configured to perform switching based on the line voltage zero cross to supply a load voltage. The electronic device further includes load voltage measuring circuitry configured to measure the load voltage. The electronic device additionally includes a processor configured to determine a load type based on the load voltage measurement and configured to control the switching circuitry to drive the load based on the load type. An electronic device for detecting load coupling is also described. The electronic device includes load voltage measuring circuitry configured to measure load voltage without activating the load voltage. The electronic device also includes a processor configured to determine whether a load is coupled based on the load voltage measurement.
