The invention provides a Boost circuit, a boost device, electric vehicle charging equipment and an electric vehicle. A new topological structure of the Boost circuit is adopted. According to the topological structure, a boost module in a Boost circuit is constructed through a first inductor module, a second inductor module, a first capacitor module, a second capacitor module and a first diode module, and the second end of the first inductor module is connected with the first end of a switching tube. When the switching tube is switched off, the second terminal voltage of the first inductance module is smaller than the output voltage. Therefore, under the condition of the same voltage gain, the voltage stress on the switch tube can be reduced, so that the damage of circuit elements can be reduced, and the operation stability can be improved.
本申请提供了一种Boost升压电路、升压装置、电动汽车充电设备及电动汽车,采用了新的Boost升压电路的拓扑结构。该拓扑结构通过第一电感模块、第二电感模块、第一电容模块、第二电容模块和第一二极管模块构建Boost升压电路中的升压模块,且第一电感模块的第二端连接开关管的第一端。当开关管关断时,第一电感模块的第二端电压小于输出电压。如此,在电压增益相同的情况下,本申请可以降低开关管受到的电压应力,从而可减少电路元件损坏,进而可提高运行稳定性。
