When current flows from a second node to a first node, the high withstand voltage transistor turns on and the low withstand voltage transistor turns off, causing current to flow through a built-in diode of the low withstand voltage transistor. Since current does not flow through the parasitic diode of the high withstand voltage transistor, the recovery current is reduced. Furthermore, since a first delay circuit including resistors and a diode is connected to the gate electrode of the high withstand voltage transistor, and a second delay circuit including resistors and a diode is connected to the gate electrode of the low withstand voltage transistor, precise adjustment of the switching speed during switching operation is possible, and losses are reduced."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Switching power supply device, and inverter, converter, and solar power controller including same","description":"A highly efficient and low-cost switching power supply device includes a high withstand voltage transistor and a low withstand voltage transistor.
