The power factor correction circuit is configured to generate, based on a first alternating-current signal, a direct-current signal. The synchronizing signal generator is configured to generate, based on the first alternating-current signal, a synchronizing signal that is in synchronization with the first alternating-current signal. The alternating-current signal generator includes a switching section, and is configured to generate, based on the direct-current signal, a second alternating-current signal. The switching section is configured to perform, based on the synchronizing signal, a switching operation. The second alternating-current signal has a variable effective voltage value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power supply unit and image forming apparatus","description":"Provided is a power supply unit that includes a power factor correction circuit, a synchronizing signal generator, an alternating-current signal generator.
