发明名称 ゼロクロス検知回路を有する電源、及び、画像形成装置
摘要 A power supply includes a first capacitor, a resistor for discharging an electric charge of the first capacitor and for detecting zero crossing of the AC voltage input from the AC power supply, a second capacitor, and a frame ground o and a discharge resistor having a resistance value smaller than the resistor and configured to discharge an electric charge of the second capacitor, and switches between a state where a current to the discharge resistor is cut off and a state where a current flows through the discharge resistor.
