The control circuit includes a current detection circuit that generates a first current detection value indicating an amount of current of a first current flowing through a first phase of the three-phase inverter. The current detection circuit can generate the first current detection value, based on a voltage drop of a resistance component of a wire existing on a path of the first current, the wire being formed from a material containing copper, or based on a voltage drop of a first resistance that is an on-resistance of an arm of the first phase, and can use, as a standard, a current detection value based on a voltage drop of the external resistance to calibrate the first current detection value based on the voltage drop of the first resistance."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Control circuit of three-phase DC motor","description":"Disclosed herein is a control circuit of a three-phase DC motor used along with an external resistance and a three-phase inverter.
