Description

technical field [0001] This patent relates to the technical field of power electronics, in particular to a buck-boost device and a buck-boost method applied to a high-power pulse power supply system. Background technique [0002] In the high-power pulse power system, the input voltage range of the buck-boost device is 960V to 1402V, and the output voltage is required to rise to 1800V in a short time, and then stabilize at about 800V, during which the current remains stable. Therefore, when the input voltage is higher than the output voltage, the input voltage needs to be stepped down; and when the input voltage is lower than the output voltage, the input voltage needs to be boosted. In order to realize the normal power supply of the energy storage device to the system, a buck-boost circuit is usually arranged between the energy storage device and the load, which can boost or step down the input voltage to obtain the output voltage required by the load. [0003] At present, ...
