1results about How to "Guaranteed not to overheat" patented technology

This application discloses a BOOST converter, a hybrid electric system, and a control method, comprising: a first terminal of a first inductor and a first terminal of a second inductor both connected to the positive terminal of a DC power supply; a second terminal of the first inductor connected to the first terminal of a bus capacitor via a second switching transistor; a second terminal of the second inductor connected to the first terminal of the bus capacitor via a third switching transistor; a first switching transistor connected between the second terminal of the first inductor and the negative terminal of the DC power supply; and a fourth switching transistor connected between the second terminal of the second inductor and the negative terminal of the DC power supply. In the event of a BOOST converter failure, all four switching transistors are blocked. When the voltage difference between the DC power supply and the bus capacitor is less than or equal to a preset voltage threshold, the second and third switching transistors are turned on to protect them. This ensures that the body diode does not overheat and avoids excessive inrush current.
