PROBLEM TO BE SOLVED: To provide a charging device and a program therefor which suppress a turbulence of output waveform and a reduction in power factor.SOLUTION: In a charging device 10, if a timing Ta of a timer interrupt by which an input voltage detection section detects a full-wave-rectified waveform of input voltage is an immediate timing Ta (1) after a zero crossing timing Tb, a delay time Tdly from the zero crossing timing Tb to the immediate timing Ta (1) is calculated, and a storage location of memory for storing an inverse pattern value at the immediate timing Ta (1) is shifted in a time lapse direction by a shift amount corresponding to the delay time Tdly. If the timing Ta of the timer interrupt by which the input voltage detection section detects a full-wave-rectified waveform of input voltage is another timing Ta (2) later than the immediate timing Ta (1), a storage location of memory for storing an inverse pattern value at the different timing Ta (2) is shifted in the time lapse direction by the shift amount corresponding to the delay time Tdly calculated as to the immediate timing Ta (1). |
