Power supply device and image formation apparatus
A power supply device includes: a power supply part to convert an AC voltage from an AC power source into a direct current and output a DC voltage; a zero cross detector to detect zero cross timings of AC voltage; and a power supply controller to control supply of the AC voltage to the power supply part and the zero cross detector based on the zero cross timing.
