One end of the second switching element is connected with one end portion of a primary winding. The other end of the second switching element is connected with one end portion of the resonance capacitor. The primary winding and the resonance capacitor are resonated with each other by alternately operating the first and second switching elements to supply electric power to a load connected with a secondary winding of the transformer. The primary winding includes a first primary winding and a second primary winding. Depending on the load, the switch connects or disconnects between the first primary winding and the resonance capacitor, or connects or disconnects between the second primary winding and said resonance capacitor."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power source device and image forming apparatus","description":"A power source device includes a transformer, a first switching element and a second switching element, a resonance capacitor, and a switch.
