摘要： A voltage transforming device is provided, which includes: a first voltage transforming module, configured to perform a pre-stage voltage transformation on an input DC voltage to output an isolated DC voltage, in which the pre-stage voltage transformation includes a primary transformation that converts the input DC voltage to a to-be-transformed AC voltage, a working period of the primary transformation includes a first half period and a second half period, and a dead time exists when a first half period and a second half period are switched between each other; a capacitor filtering module, configured to perform capacitor filtering compensation on the isolated DC voltage in the dead time to output a stable intermediate DC voltage; and a second voltage transforming module, configured to perform at least two separate post-stage voltage transformations on the intermediate DC voltage to output DC voltages required by at least two loads.

A voltage transforming method and a power supply system are also provided. Thereby, the decoupling of the pre-stage and post-stage working modes is achieved, and the interference suffered during voltage transformation is reduced.
