Abstract
Provided is a circuit apparatus including a power conversion circuit and a transmission apparatus, the transmission apparatus transmitting a signal from the power conversion circuit, the power conversion circuit having an alarm signal generation unit which generates an alarm signal indicating whether the power conversion circuit is in a preset state, and a state signal generation unit which generates a state signal having an amplitude different from that of the alarm signal and indicating a state of the power conversion circuit. The power conversion circuit may further have an output terminal which outputs an output signal in which the alarm signal and the state signal are superimposed.
