Abstract: The present disclosure discloses a voltage regulating apparatus, including a pre-stage circuit and a post-stage circuit. The pre-stage circuit receives an input voltage and outputs an intermediate bus voltage, and the post-stage circuit receives the intermediate bus voltage and outputs an output voltage. The post-stage circuit includes a plurality of post-stage converters, the post-stage converters are connected in parallel in an interleaved manner. In this way, the post-stage circuit has a small inductance, thereby reducing the volume of the apparatus and increasing the power density of the apparatus.
