Abstract
The power supply device according to the present invention converts alternating-current power into direct-current power, and supplies the direct-current power to a load. Further, the power supply device includes a buffer, a control section, a rectifier circuit, a smoothing circuit, and a switch. After a predetermined zero cross point is detected, the control section uses in common, over a predetermined period of the alternating-current power, predetermined parameters retained in the buffer in calculating a timing at which a PAM interrupt pulse is generated.
