Fast Transient

A single-phase two-switch SEPIC AC to DC converter is proposed in this paper. The boosting supply of the input is controlled by PWM of the power stage, while the desired DC output is PWM controlled. Since both the input boost supply and the output supply can be controlled independently, a fast transient response can be maintained at both the input for active current wave shaping and at the output for good output regulation. In addition, independent control of the multiple outputs provides the strong decoupling necessary and hence good transient response. Finally, some experimental results are presented for verification.
