Abstract AC-DC converters typically have two converter stages - an AC-DC stage operating with power factor correction (PFC) and an isolated DC-DC stage. Researchers have proposed various integrated converters that combine the two stages into a single converter that simultaneously performs both AC-DC conversion with PFC and DC-DC conversion. In the case of voltage-fed integrated converters, however, the primary-side DC bus voltage is left unregulated, which can result in several converter performance problems such as excessive intermediate DC bus voltage and distorted input current. A new integrated voltage fed PWM single-stage converter that does not have these problems and can be used for high output power and at the same time follow IEC1000-3-4 harmonic limits and will have excellent input power factor (>0.98) will be proposed in the paper. The paper will explain the operation of the converter in detail, discuss its features, and explain how the converter can be designed. Results obtained from an experimental prototype that confirm the feasibility of the proposed converter will be presented in the paper.
