Abstract:
A detection apparatus has an alternating-current voltage input unit and a generation circuit. The generation circuit generates a superimposition signal in which information indicating a timing of a zero cross in an alternating-current voltage inputted into the input unit and information indicating a voltage level of the alternating-current voltage are superimposed.

Claim (Index 12):
The detection apparatus according to  claim 3 , wherein\n the first edge circuit has a rectification smoothing circuit that generates a direct-current voltage by rectifying and smoothing the alternating-current voltage, and a first switch element that has a control terminal that operates by being supplied the direct-current voltage and to which a voltage correlated with the alternating-current voltage is applied, and that conducts electricity when the voltage correlated to the alternating-current voltage exceeds a threshold, and does not conduct electricity if the voltage correlated to the alternating-current voltage does not exceed the threshold, and the second edge circuit has a first voltage dividing unit that generates a voltage that is correlated to the alternating-current voltage by dividing the alternating-current voltage; a delay circuit that delays a phase of the alternating-current voltage; an addition circuit that adds the voltage outputted from the first voltage dividing unit and the voltage outputted from the delay circuit; and a second switch element that has a control terminal to which the voltage outputted from the addition circuit is applied and that switches between a conductive state and a non-conductive state in accordance with the voltage applied to the control terminal; and a third switch element that has a control terminal to which is applied a direct-current voltage which is generated from the alternating-current voltage and for which the second switch element controls application and non-application of the direct-current voltage, and that is connected in parallel with the first switch element, and the first edge circuit generates the first edge that indicates the timing of the zero cross by the first switch element transitioning from a conductive state to a non-conductive state, and the second edge circuit generates the second edge that indicates the voltage level by the third switch element transitioning from a conductive state to a non-conductive state by the second switch element transitioning from a non-conductive state to a conductive state in accordance with the voltage level of the alternating-current voltage when the first switch element is in a state in which the first switch element can conduct electricity.
