Conversion circuit includes a first capacitor, a first series circuit, a second series circuit, a third series circuit, a second diode and a Zener diode. First series circuit includes a first inductor and a switching element connected in series with each other. Second series circuit includes a second capacitor and a second inductor connected in series with each other. Third series circuit includes a first diode and a third capacitor connected in series with each other. First series circuit is electrically connected between both ends of first capacitor. Second series circuit is electrically connected in parallel with switching element. A cathode of Zener diode is connected with a connection point of first inductor and second capacitor. Zener diode has a Zener voltage larger than an output voltage of conversion circuit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"DC power supply device and lighting system using same","description":"A DC power supply device includes a rectifier circuit, a conversion circuit and a control circuit.
