摘要： A power converter includes: a solid-state transformer having a DC input and isolated DC outputs; a half bridge converter stage for each isolated DC output of the solid-state transformer, wherein an input of each half bridge converter stage is connected to the corresponding isolated DC output and an output of the half bridge converter stages are electrically connected in a cascade configuration; an output inductor shared by the half bridge converter stages and configured to deliver an output current; and a controller configured to implement phase shift control of the half bridge converter stages relative to one another, based on the number of half bridge converter stages and an output voltage of the power converter being regulated, such that each half bridge converter stage processes the full output current but only a fraction of the output voltage. Methods of controlling the power converter are also described.

摘要： A circuit for use in a switched mode power supply is described herein. In accordance with one embodiment the circuit includes a dual-boost power-factor correction (PCF) converter having an active rectifier stage with a first and a second rectifier transistor, a first boost stage with a first inductor and a first transistor, and a second boost stage with a second inductor and a second transistor. The circuit further includes an active rectifier controller circuit configured to generate a first and a second control signal for driving the first and, respectively, the second rectifier transistor on and off in accordance with an AC input voltage. Further, the circuit includes a PFC controller circuit configured to generate a pulse-width-modulated (PWM) control signal that is based on an output voltage of the first and the second boost stage and which is further based on a current sense signal representing the current passing through the active rectifier stage. A logic circuit is configured to generate a third control signal for the first transistor of the first boost stage and a fourth control signal for the second transistor of the second boost stage based on the PWM control signal and at least one of the first and the second control signals. Moreover, a related method is described.
