The first zero-crossing detector detects zero-crossing timing of an alternating voltage of power supplied from a commercial power supply and outputs a voltage zero-crossing signal. The current detector detects current of the power. The second zero-crossing detector detects zero-crossing timing of the current detected by the current detector and outputs a current zero-crossing signal. A power factor is obtained based on a phase difference between the voltage zero-crossing signal and the current zero-crossing signal, and active power is calculated based on a root-mean-square value of the alternating voltage, a root-mean-square value of the current, and the obtained power factor."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power detection device, image forming apparatus, and power detection method","description":"A power detection device includes a first zero-crossing detector, a current detector, and a second zero-crossing detector.
