Problems solved by technology

However, when the first electronic switch 20 disconnects the tap 20 from the negative pole of the power supply V1, the leakage inductance generated by the first inductance L1 makes the voltage on the tap 20 larger, so that the first electronic switch 20 needs to use a withstand voltage higher value switching elements, thus making the cost of the circuit higher

Abstract

The invention discloses a boost topology circuit and a power supply boost device with the same. The boost topology circuit comprises a power supply and a boost sub circuit which is used for boosting the power supply. The boost sub circuit comprises a first inductor and a first electronic switch, wherein a tap electrically connected with a coil of the first inductor is positioned on the first inductor, the first electronic switch is used for controlling the tap to be connected with a negative electrode of the power supply. The boost topology circuit further comprises a second electronic switch which is used for controlling the tap to be connected with an output end of the boost sub circuit when the first electronic switch is cut down. The boost topology circuit reduces voltages resistance of a switch element in the first electronic switch so as to reduce cost.
