Abstract:
An AC voltage detection device has a rectifying circuit configured to rectify an AC voltage output from an AC power source, a voltage-pulse conversion circuit configured to convert a rectified voltage rectified in the rectifying circuit to a first pulse signal having a period shorter than a half of a period of the AC voltage, a pulse transmission circuit configured to perform signal transmission with electrical insulation by converting the first pulse signal to a physical signal other than an electrical signal and converting the physical signal to a second pulse signal being an electrical signal, and a controller to which the second pulse signal is input. The controller calculates the voltage value of the AC voltage from a characteristic value of the second pulse signal.

Claim (Index 14):
The AC voltage detection device according to  claim 13 ,\n wherein the two duty ratios for calculating the moment in time when the AC voltage is 0V are consecutively detected, and one of the two duty ratios is a value detected when the AC voltage is closest to 0V, and the other is a value detected when the AC voltage is second closest to 0V.
