A supply switching circuit has a contactor that switches between supplying and not supplying DC power to the inverter circuit. A control calculator outputs a supply signal causing the contactor to supply the DC power. A memory holds charge history information that indicates a history of incomplete charging of the filter capacitor. When a supply signal is outputted from the control calculator, a supply controller controls the contactor on the basis of the charge history information."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power conversion device","description":"An inverter circuit has a main circuit for converting DC power into output electric power and outputting the output electric power, and a filter capacitor connected in parallel with the main circuit.
